The emoji was predated by the emoticon,{{cite news| url=https://www.independent.co.uk/life-style/gadgets-and-tech/news/happy-30th-birthday-emoticon-8120158.html| title=Happy 30th Birthday Emoticon!| date=September 8, 2012| newspaper=Independent| access-date=November 30, 2017}} a concept implemented in 1982 by computer scientist Scott Fahlman when he suggested text-based symbols such as :-) and :-( could be used to replace language.{{Citation | title = -) turns 25| publisher = Associated Press| date = 2007-09-20| url = http://www.cnn.com/2007/TECH/09/18/emoticon.anniversary.ap/index.html| access-date = 2007-09-20 |archive-url =https://web.archive.org/web/20071012051803/http://www.cnn.com/2007/TECH/09/18/emoticon.anniversary.ap/index.html |archive-date = 2007-10-12}} Theories about language replacement can be traced back to the 1960s, when Russian novelist and professor Vladimir Nabokov stated in an interview with The New York Times: "I often think there should exist a special typographical sign for a smile — some sort of concave mark, a supine round bracket."{{Citation| last = Nabokov| first = Vladimir| year = 1973| title = Strong Opinions| pages = 133–134| isbn = 0-679-72609-8| location = New York| url-access = registration| url = https://archive.org/details/isbn_9780679726098 |publisher=Vintage Books }} It did not become a mainstream concept until the 1990s, when Japanese, American, and European companies began developing Fahlman's idea.{{cite web| url=http://www.rd.com/culture/history-of-emoji/| title=Why Do We Use Emojis Anyway?

The first emoji are a matter of contention due to differing definitions and poor early documentation. It was previously widely considered that DoCoMo had the first emoji set in 1999, but an Emojipedia blog article in 2019 brought SoftBank's earlier 1997 set to light. More recently, in 2024, earlier emoji sets were uncovered on portable devices by Sharp Corporation and NEC{{Cite book |title=NEC 電子手帳 PI-ET1 取扱説明書 |publisher=NEC Corporation |year=1990 |pages=131 |language=Japanese |trans-title=NEC Electronic Notebook PI-ET1 Instruction Manual |chapter=システム外字数 |trans-chapter=Non System Kanji}} in the early 1990s, with the 1988 Sharp PA-8500 harboring what can be defined as the earliest known emoji set that reflects emoji keyboards today.{{Cite book |title=Sharp 電子手帳 PA-8500 取扱説明書 |publisher=SHARP Corporation |year=1988 |pages=201 |language=Japanese |trans-title=Sharp Electronic Notebook PA-8500 Operating Instructions |chapter=記号一覧表 |trans-chapter=Symbol List}}

Wingdings, a font invented by Charles Bigelow and Kris Holmes, was released by Microsoft in 1990.{{cite web |last1=Edwards |first1=Phil |title=Why the Wingdings font exists |url=https://www.vox.com/2015/8/25/9200801/wingdings-font-history |publisher=Vox |date=August 26, 2015}} It could be used to send pictographs in rich text messages, but would only load on devices with the Wingdings font installed.{{cite web |title=Correcting the Record on the First Emoji Set |url=https://blog.emojipedia.org/correcting-the-record-on-the-first-emoji-set/ |publisher=Emojipedia |date=March 8, 2019}} In 1995, the French newspaper {{Lang|fr|Le Monde}} announced that Alcatel would be launching a new phone, the BC 600. Its welcome screen displayed a digital smiley face, replacing the usual text seen as part of the "welcome message" often seen on other devices at the time.{{cite news |title=Souriez! Le GSM présente un nouveau visage |publisher=Le Monde |date=November 7, 1995 |language=fr|page=13}} In 1997, SoftBank's J-Phone arm launched the SkyWalker DP-211SW, which contained a set of 90 emoji. Its designs, each measuring 12 by 12 pixels, were monochrome, depicting numbers, sports, the time, moon phases, and the weather. It contained the Pile of Poo emoji in particular. The J-Phone model experienced low sales, and the emoji set was thus rarely used.{{Cite journal | last=Alt | first=Matt | title=Why Japan Got Over Emojis | journal=Slate | url=https://slate.com/technology/2015/12/emojis-are-no-longer-cool-in-japan.html | date=December 7, 2015 | access-date=January 22, 2019 }}

In 1999, Shigetaka Kurita created 176 emoji as part of NTT DoCoMo's i-mode, used on its mobile platform.{{cite magazine|last=Steinmetz|first=Katy|url=https://time.com/4114886/oxford-word-of-the-year-2015-emoji/|title=Oxford's 2015 Word of the Year Is This Emoji|magazine=Time|date=November 16, 2015|access-date=July 28, 2017}}{{cite web|url=https://nymag.com/daily/intelligencer/2014/11/emojis-rapid-evolution.html|title=Smile, You're Speaking Emoji|author=Sternbergh, Adam|date=November 16, 2014}}{{cite web|last1=Negishi|first1=Mayumi|title=Meet Shigetaka Kurita, the Father of Emoji|url=https://blogs.wsj.com/japanrealtime/2014/03/26/meet-shigetaka-kurita-the-father-of-emoji|work=The Wall Street Journal|date=March 26, 2014|access-date=August 16, 2015}} They were intended to help facilitate electronic communication and to serve as a distinguishing feature from other services. Due to their influence, Kurita's designs were once claimed to be the first cellular emoji; however, Kurita has denied that this is the case.{{cite web |url=https://emojitimeline.com/ |title=Emoji Timeline |first=Daniel |last=Hånberg Alonso}}{{cite web |title=日本のモバイル端末における絵文字はポケベルが最初ですが、ケータイに関しては私が開発したドコモの絵文字が最初ではなく、J-PHONEのパイオニアDP-211SWが最初だったと思います. |first=Shigetaka |last=Kurita |author-link=Shigetaka Kurita |website=Twitter |date=2019-01-03 |url=https://twitter.com/sigekun/status/1080848236653334529}} According to interviews, he took inspiration from Japanese manga where characters are often drawn with symbolic representations called manpu (such as a water drop on a face representing nervousness or confusion), and weather pictograms used to depict the weather conditions at any given time. He also drew inspiration from Chinese characters and street sign pictograms.{{cite web|title=NTT DoCoMo Emoji List|url=https://www.nttdocomo.co.jp/service/imode_mail/function/pictograph|publisher=nttdocomo.co.jp}}{{cite web|first=Mamiko |last=Nakano |translator1=Mitsuyo Inaba Lee |title=Why and how I created emoji: Interview with Shigetaka Kurita |url=http://ignition.co/105 |website=Ignition |access-date=August 16, 2015 |url-status=dead |archive-url=https://web.archive.org/web/20160610220635/http://ignition.co/105 |archive-date=June 10, 2016 }} The DoCoMo i-Mode set included facial expressions, such as smiley faces, derived from a Japanese visual style commonly found in manga and anime, combined with kaomoji and smiley elements.{{cite journal |last1=Moschini |first1=Ilaria |title=The "Face with Tears of Joy" Emoji: A Socio-Semiotic and Multimodal Insight into a Japan-America Mash-Up |journal=HERMES: Journal of Language and Communication in Business |date=29 August 2016 |issue=55 |pages=11–25 |doi=10.7146/hjlcb.v0i55.24286 |url=https://www.researchgate.net/publication/307442698 |doi-access=free |access-date=14 November 2020 |archive-date=23 January 2021 |archive-url=https://web.archive.org/web/20210123200221/https://www.researchgate.net/publication/307442698_The_Face_with_Tears_of_Joy_Emoji_A_Socio-Semiotic_and_Multimodal_Insight_into_a_Japan-America_Mash-Up |url-status=live }} Kurita's work is displayed in the Museum of Modern Art in New York City.{{cite web |last1=Ness |first1=Amanda |title=Look Who's Smiley Now: MoMA Acquires Original Emoji |url=https://www.nytimes.com/2016/10/27/arts/design/look-whos-smiley-now-moma-acquires-original-emoji.html |newspaper=The New York Times |date=October 26, 2016}}

Kurita's emoji were brightly colored, albeit with a single color per glyph. General-use emoji, such as sports, actions, and weather, can readily be traced back to Kurita's emoji set.{{Cite web|url=https://www.theguardian.com/technology/2016/oct/27/emoji-inventor-shigetaka-kurita-moma-new-york-text|title=The inventor of emoji on his famous creations – and his all-time favorite|last=McCurry|first=Justin|date=2016-10-27|website=The Guardian |language=en |access-date=2018-06-17}} Notably absent from the set were pictograms that demonstrated emotion. The yellow-faced emoji in current use evolved from other emoticon sets and cannot be traced back to Kurita's work. His set also had generic images much like the J-Phones. Elsewhere in the 1990s, Nokia phones began including preset pictograms in its text messaging app, which they defined as "smileys and symbols".{{cite web |title=Nokia 3310 User Guide |url=https://www.nokia.com/phones/en_gb/support/api/pdf/nokia-3310-user-guide |publisher=Nokia}} A third notable emoji set was introduced by Japanese mobile phone brand au by KDDI.{{cite web|url=https://www.fastcompany.com/3037803/the-oral-history-of-the-poop-emoji-or-how-google-brought-poop-to-america|title=The Oral History Of The Poop Emoji (Or, How Google Brought Poop To America)|website=Fast Company|last=Schwartzberg|first=Lauren|date=18 November 2014|language=en|access-date=29 March 2017}}

The basic 12-by-12-pixel emoji in Japan grew in popularity across various platforms over the next decade. While emoji adoption was high in Japan during this time, the competitors failed to collaborate to create a uniform set of emoji to be used across all platforms in the country.{{cite web |last1=Blagdon |first1=Jeff |title=How emoji conquered the world |url=https://www.theverge.com/2013/3/4/3966140/how-emoji-conquered-the-world |publisher=The Verge |date=March 4, 2013}}

The Universal Coded Character Set (Unicode), controlled by the Unicode Consortium and ISO/IEC JTC 1/SC 2, had already been established as the international standard for text representation (ISO/IEC 10646) since 1993, although variants of Shift JIS remained relatively common in Japan. Unicode included several characters which would subsequently be classified as emoji, including some from North American or Western European sources such as DOS code page 437, ITC Zapf Dingbats, or the WordPerfect Iconic Symbols set.{{cite web |title=Unicode 1.1 Emoji List |url=https://emojipedia.org/unicode-1.1/ |publisher=Emojipedia}}{{cite web |url=https://corp.unicode.org/pipermail/unicode/2021-February/009307.html |last=Whistler |first=Ken |date=2021-02-01 |title=Re: Origins of ⌚ U+231A WATCH and ⌛ U+231B HOURGLASS |work=Unicode Mail List Archives}} Unicode coverage of written characters was extended several times by new editions during the 2000s, with little interest in incorporating the Japanese cellular emoji sets (deemed out of scope),{{cite web |url=https://unicode.org/emoji/principles.html |title=Emoji Encoding Principles |publisher=Unicode Consortium}} although symbol characters which would subsequently be classified as emoji continued to be added. For example, Unicode 4.0 contained 16 new emoji, which included direction arrows, a warning triangle, and an eject button.{{cite web |title=Unicode 4.0 List |url=https://emojipedia.org/unicode-4.0/ |publisher=Emojipedia}} Besides Zapf Dingbats, other dingbat fonts such as Wingdings or Webdings also included additional pictographic symbols in their own custom pi font encodings; unlike Zapf Dingbats, however, many of these would not be available as Unicode emoji until 2014.

Nicolas Loufrani applied to the US Copyright Office in 1999 to register the 471 smileys that he created.{{cite web |title=The Untold Story Behind the Emoji Phenomeon |date=March 10, 2022 |url=https://www.hooksmagazine.com/post/silver-screen-the-untold-story-behind-the-emoji-phenomenon |work=Hooks magazine}} Soon after he created The Smiley Dictionary, which not only hosted the largest number of smileys at the time, it also categorized them.{{cite web |title=Historical capture of SmileyDictionary.com from 2001 |url=https://www.smileydictionary.com |publisher=Wayback Machine |archive-url=https://web.archive.org/web/20010331043601/http://www.smileydictionary.com/|archive-date=March 31, 2001}} The desktop platform was aimed at allowing people to insert smileys as text when sending emails and writing on a desktop computer.{{cite web |last1=Speare-Cole |first1=Rebecca |title=Man behind iconic smiley face symbol says limited number of emojis restricts freedom of speech |date=November 10, 2019 |url=https://www.standard.co.uk/news/uk/man-behind-iconic-smiley-face-symbol-says-limited-number-of-emojis-restricts-freedom-of-speech-a4282786.html |publisher=Evening Standard}} By 2003, it had grown to 887 smileys and 640 ascii emotions.{{cite web |title=From smiley to emoji, 20 years of history |date=August 6, 2017 |url=https://fleetpeople.es/de-smiley-a-emoji-20-anos-de-historia/ |publisher=Fleet People}}

There were competitors, but The Smiley Dictionary was the most popular. Platforms such as MSN Messenger allowed for customisation from 2001 onwards, with many users importing emoticons to use in messages as text. These emoticons would eventually go on to become the modern-day emoji. It was not until MSN Messenger and BlackBerry noticed the popularity of these unofficial sets and launched their own from late 2003 onwards.{{cite web |last1=Li |first1=Shirley |title=The Life And Times of MSN Messenger, As Told Through MSN Emoticons |date=August 29, 2014 |url=https://www.theatlantic.com/technology/archive/2014/08/the-life-and-times-of-msn-messenger-as-told-through-msn-emoticons/379371/ |work=The Atlantic}}

The first American company to take notice of emoji was Google beginning in 2007. In August 2007, a team made up of Mark Davis and his colleagues Kat Momoi and Markus Scherer began petitioning the Unicode Technical Committee (UTC) in an attempt to standardise the emoji.{{cite magazine |last1=Pardes |first1=Arielle |title=The Wired Guide to Emoji |url=https://www.wired.com/story/guide-emoji/ |magazine=Wired |date=February 1, 2018}} The UTC, having previously deemed emoji to be out of scope for Unicode, made the decision to broaden its scope to enable compatibility with the Japanese cellular carrier formats which were becoming more widespread. Peter Edberg and Yasuo Kida joined the collaborative effort from Apple Inc. shortly after, and their official UTC proposal came in January 2009 with 625 new emoji characters. Unicode accepted the proposal in 2010.

Pending the assignment of standard Unicode code points, Google and Apple implemented emoji support via Private Use Area schemes. Google first introduced emoji in Gmail in October 2008, in collaboration with au by KDDI, and Apple introduced the first release of Apple Color Emoji to iPhone OS on 21 November 2008.{{Cite web|url=https://blog.emojipedia.org/apple-emoji-turns-10/|title=Apple Emoji Turns 10|last=Burge|first=Jeremy|date=21 November 2018|website=Emojipedia|language=en|access-date=31 December 2018}} Initially, Apple's emoji support was implemented for holders of a SoftBank SIM card; the emoji themselves were represented using SoftBank's Private Use Area scheme and mostly resembled the SoftBank designs.{{cite web |url=https://emojipedia.org/apple/iphone-os-2.2/ |title=Apple iPhone OS 2.2 |work=Emojipedia |author=Emojipedia}} Gmail emoji used their own Private Use Area scheme in a supplementary Private Use plane.{{cite web |url=https://umihotaru.work/nishiki-teki_pua.pdf |title=Nishiki-teki Version 3.90r (2021-09-25)—6,463 characters in the Private Use Areas}}

Separately, a proposal had been submitted in 2008 to add the ARIB extended characters used in broadcasting in Japan to Unicode. This included several pictographic symbols.{{citation|mode=cs1 |url=https://www.unicode.org/L2/L2008/08077r2-japanese-tv.pdf |title=Japanese TV Symbols |id=UTC L2/08-077R2 / ISO/IEC JTC1/SC2/WG2 N3397 |last=Suignard |first=Michel |date=2008-03-11}} These were added in Unicode 5.2 in 2009, a year before the cellular emoji sets were fully added; they include several characters which either also appeared amongst the cellular emoji{{cite web |url=https://www.unicode.org/L2/L2010/10132-emojidata.pdf |id=UTC L2/10-132 |title=Emoji Symbols: Background Data—Background data for Proposal for Encoding Emoji Symbols |first1=Markus |last1=Scherer |first2=Mark |last2=Davis |first3=Kat |last3=Momoi |first4=Darick |last4=Tong |first5=Yasuo |last5=Kida |first6=Peter |last6=Edberg}} or were subsequently classified as emoji.{{cite web |url=https://emojipedia.org/unicode-5.2/ |title=Unicode 5.2 Emoji List |work=Emojipedia |author=Emojipedia |author-link=Emojipedia}}

After iPhone users in the United States discovered that downloading Japanese apps allowed access to the keyboard, pressure grew to expand the availability of the emoji keyboard beyond Japan.{{cite web|last=Cocozza|first=Paula|url=https://www.theguardian.com/technology/2015/nov/17/crying-with-laughter-how-we-learned-how-to-speak-emoji|title=Crying with laughter: how we learned how to speak emoji|work=The Guardian|date=November 17, 2015|access-date=July 28, 2017|archive-date=May 6, 2019|archive-url=https://web.archive.org/web/20190506022028/https://www.theguardian.com/technology/2015/nov/17/crying-with-laughter-how-we-learned-how-to-speak-emoji|url-status=live}} The Emoji application for iOS, which altered the Settings app to allow access to the emoji keyboard, was created by Josh Gare in February 2010.{{Cite web|title=App Shopper: Emoji|url=http://appshopper.com/social-networking/emoji|website=App Shopper|access-date=2017-03-01}} Before the existence of Gare's Emoji app, Apple had intended for the emoji keyboard to only be available in Japan in iOS version 2.2.{{Cite web|title=Apple releases iPhone Software v2.2|url=http://appleinsider.com/article/?id=10447|website=AppleInsider|access-date=2017-02-28}}

Throughout 2009, members of the Unicode Consortium and national standardization bodies of various countries gave feedback and proposed changes to the international standardization of the emoji. The feedback from various bodies in the United States, Europe, and Japan agreed on a set of 722 emoji as the standard set. This would be released in October 2010 in Unicode 6.0.{{cite web|url=https://www.unicode.org/faq/emoji_dingbats.html|title=FAQ – Emoji & Dingbats|work=unicode.org}} Apple made the emoji keyboard available to those outside of Japan in iOS version 5.0 in 2011.{{Cite web|title=Standard Emoji keyboard arrives to iOS 5, here's how to enable it|url=https://9to5mac.com/2011/06/08/standard-emoji-keyboard-arrives-to-ios-5-heres-how-to-enable-it/|website=9to5Mac|date=June 8, 2011|access-date=2017-02-28}} Later, Unicode 7.0 (June 2014) added the character repertoires of the Webdings and Wingdings fonts to Unicode, resulting in approximately 250 more Unicode emoji.{{cite web| url=http://hexus.net/tech/news/software/71157-host-new-characters-emoji-introduced-unicode-70/| title=Host of New Characters and Emoji Introduced in Unicode 7.0| date=June 17, 2014| publisher=Hexus| access-date=November 30, 2017}}

The Unicode emoji whose code points were assigned in 2014 or earlier are therefore taken from several sources. A single character could exist in multiple sources, and characters from a source were unified with existing characters where appropriate: for example, the "shower" weather symbol (☔️) from the ARIB source was unified with an existing umbrella with raindrops character,{{cite web |url=https://www.unicode.org/L2/L2007/07391-n3341.pdf |title=Japanese TV Symbols |first=Michel |last=Suignard |date=2007-09-18 |id=UTC L2/07-391, ISO/IEC JTC 1/SC 2/WG 2 N3341}} which had been added for KPS 9566 compatibility.{{cite web |url=https://www.unicode.org/L2/L2002/02102-n2417-dprk.pdf |first=Asmus |last=Freytag |date=2002-02-13 |id=ISO/IEC JTC 1/SC 2/WG 2 N2417, UTC L2/02-102 |title=Notes on proposed Symbols from DPRK}} The emoji characters named {{Nihongo|"Rain"|"雨"|ame}} from all three Japanese carriers were in turn unified with the ARIB character. However, the Unicode Consortium groups the most significant sources of emoji into four categories:

In late 2014, a Public Review Issue was created by the Unicode Technical Committee, seeking feedback on a proposed Unicode Technical Report (UTR) titled "Unicode Emoji". This was intended to improve interoperability of emoji between vendors, and define a means of supporting multiple skin tones. The feedback period closed in January 2015.{{cite web |url=https://www.unicode.org/review/pri286/ |title=Proposed Draft UTR #51, Unicode Emoji |work=Public Review Issues |id=PRI 286 |institution=Unicode Consortium}} Also in January 2015, the use of the zero-width joiner to indicate that a sequence of emoji could be shown as a single equivalent glyph (analogous to a ligature) as a means of implementing emoji without atomic code points, such as varied compositions of families, was discussed within the "emoji ad-hoc committee".{{cite web |url=https://www.unicode.org/L2/L2015/15029r-zwj-emoji.pdf |title=ZWJ in emoji sequences as hint for single glyph |id=UTC L2/15-029R |date=2015-01-29 |first1=Peter |last1=Edberg |author2=Emoji Ad-hoc Committee}}

Unicode 8.0 (June 2015) added another 41 emoji, including articles of sports equipment such as the cricket bat, food items such as the taco, new facial expressions, and symbols for places of worship, as well as five characters (crab, scorpion, lion face, bow and arrow, amphora) to improve support for pictorial rather than symbolic representations of the signs of the Zodiac.{{efn|Older au by KDDI devices had used pictorial representations of all zodiac signs, displaying for instance the pisces sign (♓️) as a fish (🐟).

Also in June 2015, the first approved version ("Emoji 1.0") of the Unicode Emoji report was published as Unicode Technical Report #51 (UTR #51). This introduced the mechanism of skin tone indicators, the first official recommendations about which Unicode characters were to be considered emoji, and the first official recommendations about which characters were to be displayed in an emoji font in the absence of a variation selector, and listed the zero-width joiner sequences for families and couples that were implemented by existing vendors.{{cite web |url=https://www.unicode.org/reports/tr51/tr51-3-archive.html |title=Unicode Technical Report #51: Unicode Emoji |version=1.0 |date=2015-06-09 |first1=Mark |last1=Davis |author-link1=Mark Davis (Unicode) |first2=Peter |last2=Edberg |institution=Unicode Consortium}} Maintenance of UTR #51, taking emoji requests, and creating proposals for emoji characters and emoji mechanisms was made the responsibility of the Unicode Emoji Subcommittee (ESC), operating as a subcommittee of the Unicode Technical Committee.{{cite web |archive-url=https://web.archive.org/web/20150625033424/http://unicode.org/emoji/index.html#Unicode_Emoji_Subcommittee |archive-date=2015-06-25 |url-status=dead |url=http://unicode.org/emoji/index.html#Unicode_Emoji_Subcommittee |title=Unicode Emoji Subcommittee |publisher=Unicode Consortium}}{{cite web |url=http://unicode.org/emoji/techindex.html#Unicode_Emoji_Subcommittee |title=Unicode Emoji Subcommittee |publisher=Unicode Consortium}}

With the release of version 5.0 in May 2017 alongside Unicode 10.0, UTR #51 was redesignated a Unicode Technical Standard (UTS #51), making it an independent specification.{{cite web |url=https://www.unicode.org/reports/tr51/tr51-12.html |title=Unicode Technical Standard #51: Unicode Emoji |version=5.0 |date=2017-05-18 |first1=Mark |last1=Davis |author-link1=Mark Davis (Unicode) |first2=Peter |last2=Edberg |institution=Unicode Consortium}} {{as of|2017|July|post=,}} there were 2,666 Unicode emoji listed.{{cite web| url=https://www.bbc.com/news/technology-40612529| title=Emojis Honoured in World Celebration| date=July 17, 2017| publisher=BBC| access-date=November 30, 2017}} The next version of UTS #51 (published in May 2018) skipped to the version number Emoji 11.0 so as to synchronise its major version number with the corresponding version of the Unicode Standard.{{cite web |url=https://www.unicode.org/reports/tr51/tr51-14.html#Versioning |title=1.5.2 Versioning |work=Unicode Technical Standard #51: Unicode Emoji |version=11.0 |date=2018-05-21 |first1=Mark |last1=Davis |author-link1=Mark Davis (Unicode) |first2=Peter |last2=Edberg |institution=Unicode Consortium}}

The popularity of emoji has caused pressure from vendors and international markets to add additional designs into the Unicode standard to meet the demands of different cultures. Some characters now defined as emoji are inherited from a variety of pre-Unicode messenger systems not only used in Japan, including Yahoo and MSN Messenger.{{cite web|title=Emoji Additions: Animals, Compatibility, and More Popular Requests; Emoji tranche 5|url=https://www.unicode.org/L2/L2015/15054r4-emoji-tranche5.pdf|publisher=Unicode|access-date=August 18, 2015}} Corporate demand for emoji standardization has placed pressures on the Unicode Consortium, with some members complaining that it had overtaken the group's traditional focus on standardizing characters used for minority languages and transcribing historical records.{{cite web|last1=Warzel|first1=Charlie|title=Inside 'Emojigeddon': The Fight Over The Future of the Unicode Consortium|url=https://www.buzzfeed.com/charliewarzel/inside-emojigeddon-the-fight-over-the-future-of-the-unicode|website=Buzzfeed|date=April 26, 2016 |access-date=September 15, 2017}} Conversely, the Consortium thought that public desire for emoji support has put pressure on vendors to improve their Unicode support, which is especially true for characters outside the Basic Multilingual Plane, thus leading to better support for Unicode's historic and minority scripts in deployed software.

In 2022, the Unicode Consortium decided to stop accepting proposals for flag emoji, citing low use of the category and that adding new flags "creates exclusivity at the expense of others".{{Cite web |last=Daniel |first=Jennifer |date=March 28, 2022 |title=The Past and Future of Flag Emoji |url=https://blog.unicode.org/2022/03/the-past-and-future-of-flag-emoji.html |access-date=March 13, 2024 |website=blog.unicode.org}}{{Cite web |last=Tomaschek |first=Attila |date=March 29, 2022 |title=New Flag Emoji Proposals No Longer Accepted, Unicode Says |url=https://www.cnet.com/culture/internet/new-flag-emoji-proposals-no-longer-accepted-unicode-says/ |access-date=March 13, 2024 |website=CNET}} The Consortium stated that new flag emoji would still be added when their country becomes part of the ISO 3166-1 standard, with no proposal needed.

A mosquito ({{unichar|1F99F}}) emoji was added in 2018 to raise awareness for diseases spread by the insect, such as dengue and malaria.{{Cite web|url=https://ccp.jhu.edu/2017/09/18/creating-buzz-proposing-mosquito-emoji-public-health/|title=Creating Buzz: Proposing a Mosquito Emoji for Public Health|last=Desmon|first=Stephanie|date=2017-09-18|website=Johns Hopkins Center for Communication Programs|language=en-US|access-date=2019-02-11}}

Linguistically, emoji are used to indicate emotional state; they tend to be used more in positive communication. Some researchers believe emoji can be used for visual rhetoric. Emoji can be used to set emotional tone in messages. Emoji tend not to have their own meaning but act as a paralanguage, adding meaning to text. Emoji can add clarity and credibility to text.{{Cite journal |last1=Bai |first1=Qiyu |last2=Dan |first2=Qi |last3=Mu |first3=Zhe |last4=Yang |first4=Maokun |date=2019 |title=A Systematic Review of Emoji: Current Research and Future Perspectives |journal=Frontiers in Psychology |volume=10 |page=2221 |doi=10.3389/fpsyg.2019.02221 |pmid=31681068 |pmc=6803511 |issn=1664-1078|doi-access=free }}

Sociolinguistically, the use of emoji differs depending on speaker and setting. Women use emoji more than men. Men use a wider variety of emoji. Women are more likely to use emoji in public communication than in private communication. Extraversion and agreeableness are positively correlated with emoji use; neuroticism is negatively correlated. Emoji use differs between cultures: studies in terms of Hofstede's cultural dimensions theory found that cultures with high power distance and tolerance to indulgence used more negative emoji, while those with high uncertainty avoidance, individualism, and long-term orientation use more positive emoji. A 6-country user experience study showed that emoji-based scales (specifically the usage of smileys) may ease the challenges related to translation and implementation for brief cross-cultural surveys.{{Cite book |last1=Sedley |first1=Aaron |url=https://www.rti.org/rti-press-publication/language-survey-research |title=Scaling the Smileys: A Multicountry Investigation (Chapter 12) in The Essential Role of Language in Survey Research |last2=Yang |first2=Yongwei |date=2020-04-30 |publisher=RTI Press |isbn=978-1-934831-24-3 |editor-last=Sha |editor-first=Mandy |doi=10.3768/rtipress.bk.0023.2004 |doi-access=free}}

As emoji act as a paralanguage this causes a unique pattern to be seen in the bigrams, trigrams, and quadrigrams of emoji. A study conducted by Gretchen McCulloch and Lauren Gawne showed that the most common bigrams, trigrams, and quadrigrams of emoji are those that repeat the same emoji.{{Cite journal |last1=McCulloch |first1=Gretchen |last2=Gawne |first2=Lauren |date=2018 |title=Emoji Grammar as Beat Gestures |url=https://ceur-ws.org/Vol-2130/short1.pdf |journal=CEUR-WS.org |volume=2130 |pages=4}} Unlike other languages emoji frequently are repeated one after another, while in languages, such as English, it is rare to see words repeated after one another. An example of this is that a common bigram for emoji is two crying laughing emoji. Rather than being a repeated word or phrase the use of emoji after one another typically represents an emphasize of the displayed emoji's meaning instead. So, one crying laughing emoji means something is funny, two represent it's really funny, three might represent it's incredibly funny, and so forth.

{{see also|Models of communication}}

Research has shown that emoji are often misunderstood. In some cases, this misunderstanding is related to how the actual emoji design is interpreted by the viewer;{{Cite news|url=https://www.dailydot.com/debug/emoji-miscommunicate/|title=Emoji can lead to huge misunderstandings, research finds|work=Daily Dot|first=Selena|last=Larson|date=April 11, 2016|access-date=March 30, 2017}} in other cases, the emoji that was sent is not shown in the same way on the receiving side.{{Cite web|url=https://grouplens.org/blog/investigating-the-potential-for-miscommunication-using-emoji/|title=Investigating the Potential for Miscommunication Using Emoji|publisher=Grouplens|first=Hannah|last=Miller|date=April 5, 2016|access-date=March 30, 2017}}

The first issue relates to the cultural or contextual interpretation of the emoji. When the author picks an emoji, they think about it in a certain way, but the same character may not trigger the same thoughts in the mind of the receiver.{{cite web| url=https://motherboard.vice.com/en_us/article/78kzn9/what-the-emoji-youre-sending-actually-look-like-to-your-friends| title=What the Emoji You're Sending Actually Look Like to Your Friends| date=November 12, 2015| publisher=Motherboard| access-date=November 30, 2017}} For example, people in China have developed a system for using emoji subversively so that a smiley face could be sent to convey a despising, mocking, and obnoxious attitude, as the orbicularis oculi (the muscle near that upper eye corner) on the face of the emoji does not move, and the orbicularis oris (the one near the mouth) tightens, which is believed to be a sign of suppressing a smile.{{cite web|url=https://qz.com/944693/chinese-people-mean-something-very-different-when-they-send-you-a-smiley-emoji/ |title=Chinese people mean something very different when they send you a smiley emoji |website=Quartz|date=March 29, 2017}}

The second problem relates to encodes. When an author of a message picks an emoji from a list, it is normally encoded in a non-graphical manner during the transmission, and if the author and the reader do not use the same software or operating system for their devices, the reader's device may visualize the same emoji in a different way. As an example, in April 2020, British actress and presenter Jameela Jamil posted a tweet from her iPhone using the Face with Hand Over Mouth emoji (🤭) as part of a comment on people shopping for food during the COVID-19 pandemic. On Apple's iOS, the emoji expression was neutral and pensive, but on other platforms the emoji shows as a giggling face.

Researchers from the German Studies Institute at Ruhr-Universität Bochum found that most people can easily understand an emoji when it replaces a word directly – like an icon for a rose instead of the word 'rose' – yet it takes people about 50 percent longer to comprehend the emoji.{{Cite journal |last1=Scheffler |first1=Tatjana |last2=Brandt |first2=Lasse |last3=Fuente |first3=Marie de la |last4=Nenchev |first4=Ivan |date=February 2022 |title=The processing of emoji-word substitutions: A self-paced-reading study |journal=Computers in Human Behavior |language=en |publication-date=25 October 2021 |volume=127 |pages=107076 |doi=10.1016/j.chb.2021.107076|doi-access=free }}

Emoji characters vary slightly between platforms within the limits in meaning defined by the Unicode specification, as companies have tried to provide artistic presentations of ideas and objects.{{cite web|last1=Allsopp |first1=Ashleigh |title=Lost in translation: Android emoji vs iOS emoji |url=http://www.techadvisor.co.uk/opinion/mobile-phone/lost-in-translation-android-emoji-vs-ios-emoji |url-status=dead |archive-url=https://web.archive.org/web/20141228093209/http://www.techadvisor.co.uk/opinion/mobile-phone/lost-in-translation-android-emoji-vs-ios-emoji/ |archive-date=December 28, 2014 |date=December 15, 2014 |website=Tech Advisor |access-date=August 15, 2015 }} For example, following an Apple tradition, the calendar emoji on Apple products always shows July 17, the date in 2002 Apple announced its iCal calendar application for macOS. This led some Apple product users to initially nickname July 17 "World Emoji Day".{{Cite news|title = Letting Our Emojis Get in the Way|url=https://www.nytimes.com/2015/07/18/nytnow/letting-our-emojis-get-in-the-way.html|newspaper=The New York Times|date=July 17, 2015|access-date=August 25, 2015|first=Kathryn|last=Varn}} Other emoji fonts show different dates or do not show a specific one.{{cite web|title=Calendar emoji|url=http://emojipedia.org/calendar|website=Emojipedia|access-date=August 15, 2015}}

Some Apple emoji are very similar to the SoftBank standard, since SoftBank was the first Japanese network on which the iPhone launched. For example, {{unichar|1F483|DANCER|nlink=💃}} is female on Apple and SoftBank standards but male or gender-neutral on others.{{cite news|last1=Bosker|first1=Bianca|title=How Emoji Get Lost in Translation|url=https://www.huffingtonpost.com/2014/06/27/emoji-meaning_n_5530638.html|work=Huffington Post|date=June 27, 2014|access-date=August 15, 2015}}

Journalists have noted that the ambiguity of emoji has allowed them to take on culture-specific meanings not present in the original glyphs. For example, {{unichar|1F485|NAIL POLISH|nlink=💅}} has been described as being used in English-language communities to signify "non-caring fabulousness"{{cite news|last1=Hern|first1=Alex|title=How to (pretend to) be young and down with the internet|url=https://www.theguardian.com/commentisfree/2015/aug/12/how-to-be-young-internet-lol-facebook|work=The Guardian|date=August 12, 2015|access-date=August 15, 2015}} and "anything from shutting haters down to a sense of accomplishment".{{cite web|last1=Jewell|first1=Hannah|title=The 31 Most Nail Care Emoji Moments of 2014|url=https://www.buzzfeed.com/hannahjewell/the-most-nail-care-emoji-moments-of-2014|website=Buzzfeed|date=December 13, 2014|access-date=August 15, 2015}}{{cite web|first1=Alexander|last1=Abad-Santos|first2=Allie|last2=Jones|title=The Five Non-Negotiable Best Emojis in the Land|url=http://www.thewire.com/culture/2014/03/the-only-five-emojis-you-need/359646/|website=The Atlantic Wire|date=March 26, 2014|access-date=August 15, 2015|archive-date=August 20, 2016|archive-url=https://web.archive.org/web/20160820011420/http://www.thewire.com/culture/2014/03/the-only-five-emojis-you-need/359646/|url-status=dead}} Unicode manuals sometimes provide notes on auxiliary meanings of an object to guide designers on how emoji may be used, for example noting that some users may expect {{unichar|1F4BA|SEAT}} to stand for "a reserved or ticketed seat, as for an airplane, train, or theater".{{cite web|title=Miscellaneous Symbols and Pictographs|url=https://www.unicode.org/charts/beta/nameslist/n_1F300.html|website=Unicode Consortium|access-date=September 15, 2017}}

In the lead-up to the 2016 Summer Olympics, the Unicode Consortium considered proposals to add several Olympic-related emoji, including medals and events such as handball and water polo.{{cite web |url=https://www.newsweek.com/new-emoji-candidates-be-voted-spring-2016-385196 |title=New Emoji Candidates to Be Voted On in Spring 2016 |last=Ziv |first=Stan |website=Newsweek |date=20 October 2015 |access-date=1 October 2018}} By October 2015, these candidate emoji included "rifle" ({{unichar|1F946}}) and "modern pentathlon" ({{unichar|1F93B}}).{{Cite news |url=https://emojipedia.org/unicode-9.0/ |title=Unicode 9.0 Emoji List |date=31 October 2015 |work=Emojipedia |access-date=1 October 2018 |language=en |archive-url=https://web.archive.org/web/20151031233229/https://emojipedia.org/unicode-9.0/ |archive-date=2015-10-31 |url-status=dead}} However, in 2016, Apple and Microsoft opposed these two emoji, and the characters were added without emoji presentations, meaning that software is expected to render them in black-and-white rather than color, and emoji-specific software such as onscreen keyboards will generally not include them. In addition, while the original incarnations of the modern pentathlon emoji depicted its five events, including a man pointing a gun, the final glyph contains a person riding a horse, along with a laser pistol target in the corner.{{cite web |url=https://www.buzzfeed.com/charliewarzel/thanks-to-apples-influence-youre-not-getting-a-rifle-emoji |title=Thanks To Apple's Influence, You're Not Getting A Rifle Emoji |last=Warzel |first=Charlie |website=BuzzFeed |date=June 17, 2016 |access-date=October 19, 2017}}{{cite web |url=http://www.cbc.ca/news/trending/rifle-emoji-dropped-unicode-9-0-update-apple-microsoft-1.3645884 |title=Apple stops Unicode from releasing a rifle emoji, gun advocates get mad |website=CBC News |date=June 22, 2016 |access-date=October 19, 2017}}

On August 1, 2016, Apple announced that in iOS 10, the pistol emoji ({{unichar|1F52B}}) would be changed from a realistic revolver to a water pistol. Conversely, the following day, Microsoft pushed out an update to Windows 10 that changed its longstanding depiction of the pistol emoji as a toy raygun to a real revolver.{{cite web |url=https://www.engadget.com/2016/08/04/microsoft-new-real-gun-emoji/ |title=Microsoft just changed its toy gun emoji to a real pistol |last=Low |first=Cherlynn |website=Engadget |date=August 4, 2016 |access-date=October 19, 2017}} Microsoft stated that the change was made to bring the glyph more in line with industry-standard designs and customer expectations.

{{main|Implementation of emoji}}

Various, often incompatible, character encoding schemes were developed by the different mobile providers in Japan for their own emoji sets.{{cite web |url=https://www.unicode.org/Public/UCD/latest/ucd/EmojiSources.txt |title=Emoji Sources |work=Unicode Character Database |author=Unicode Consortium |author-link=Unicode Consortium}} For example, the extended Shift JIS representation F797 is used for a convenience store (🏪) by SoftBank, but for a wristwatch (⌚️) by KDDI. All three vendors also developed schemes for encoding their emoji in the Unicode Private Use Area: DoCoMo, for example, used the range U+E63E through U+E757. Versions of iOS prior to 5.1 encoded emoji in the SoftBank private use area.{{cite web |url=https://emojipedia.org/apple/ios-5.1/ |work=Emojipedia |title=Apple iOS 5.1}}{{cite web |url=https://emojipedia.org/apple/iphone-os-2.2/ |work=Emojipedia |title=Apple iPhone OS 2.2}}

Most, but not all, emoji are included in the Supplementary Multilingual Plane (SMP) of Unicode, which is also used for ancient scripts, some modern scripts such as Adlam or Osage, and special-use characters such as Mathematical Alphanumeric Symbols.{{cite web |url=https://www.unicode.org/roadmaps/smp/smp-13-0-3.html |title=Roadmap to the SMP |first1=Michael |last1=Everson |first2=Rick |last2=McGowan |first3=Ken |last3=Whistler |first4=V.S. |last4=Umamaheswaran |date=2020-07-22 |version=Revision 13.0.3}} Some systems introduced prior to the advent of Unicode emoji were only designed to support characters in the Basic Multilingual Plane (BMP) on the assumption that non-BMP characters would rarely be encountered,{{cite web |url=https://backendless.com/extended-string-data-type/ |title=How We Store Emojis in Your Database, or Why We Got Rid of the Extended String Data Type |first=Sergey |last=Chupov |date=2019-06-06 |publisher=Backendless Corporation}} although failure to properly handle characters outside of the BMP precludes Unicode compliance.{{cite book |last=Lunde |first=Ken |year=2009 |title=CJKV Information Processing |edition=2nd |page=200 |location=Sebastopol CA. |publisher=O'Reilly Media |isbn=978-0-596-51447-1}}

The introduction of Unicode emoji created an incentive for vendors to improve their support for non-BMP characters. The Unicode Consortium notes that "[b]ecause of the demand for emoji, many implementations have upgraded their Unicode support substantially", also helping support minority languages that use those features.{{cite web |url=https://unicode.org/faq/emoji_dingbats.html#EO1 |title=Don't emoji detract from the other work of the consortium? |series=Frequently Asked Questions: Emoji and Pictographs |publisher=Unicode Consortium}}

Any operating system that supports adding additional fonts to the system can add an emoji-supporting font. However, inclusion of colorful emoji in existing font formats requires dedicated support for color glyphs. Not all operating systems have support for color fonts, so, emoji might have to be rendered as black-and-white line art or not at all. There are four different formats used for multi-color glyphs in an SFNT font,{{citation|mode=cs1 |url=https://docs.microsoft.com/en-us/windows/win32/directwrite/color-fonts#what-kinds-of-color-fonts-does-windows-support |title=Color Fonts |work=Microsoft Docs |date=2018-05-31 |author=Microsoft |author-link=Microsoft}} not all of which are necessarily supported by a given operating system library or software package such as a web browser or graphical program.{{cite web |url=https://www.colorfonts.wtf/#section2 |title=What's inside color fonts? |website=Color Fonts – Get ready for the revolution!}}

Apple first introduced emoji to their desktop operating system with the release of OS X 10.7 Lion, in 2011. Users can view emoji characters sent through email and messaging applications, which are commonly shared by mobile users, as well as any other application. Users can create emoji symbols using the "Characters" special input panel from almost any native application by selecting the "Edit" menu and pulling down to "Special Characters", or by the key combination {{key press|Command|Option|T}}. The emoji keyboard was first available in Japan with the release of iPhone OS version 2.2 in 2008.{{Cite web|title=Apple releases iPhone Software v2.2|url=https://appleinsider.com/article/?id=10447|website=AppleInsider|access-date=February 28, 2017|archive-date=March 1, 2017|archive-url=https://web.archive.org/web/20170301180231/http://appleinsider.com/article/?id=10447|url-status=dead}} The emoji keyboard was not officially made available outside of Japan until iOS version 5.0.{{Cite web|title=Standard Emoji keyboard arrives to iOS 5, here's how to enable it|url=https://9to5mac.com/2011/06/08/standard-emoji-keyboard-arrives-to-ios-5-heres-how-to-enable-it/|website=9to5Mac|date=June 8, 2011|access-date=February 28, 2017}} From iPhone OS 2.2 through to iOS 4.3.5 (2011), those outside Japan could access the keyboard but had to use a third-party app to enable it.

Facebook and Twitter replace all Unicode emoji used on their websites with their own custom graphics. Prior to October 2017, Facebook had different sets for the main site and for its Messenger service, where only the former provides complete coverage. Messenger now uses Apple emoji on iOS, and the main Facebook set elsewhere.{{cite web |url=https://blog.emojipedia.org/facebook-discontinues-messenger-emojis/ |title=Facebook Discontinues Messenger Emojis |date=2 October 2017 |publisher=Emojipedia |first=Jeremy |last=Burge |url-status=live |archive-url=https://web.archive.org/web/20230924002918/https://blog.emojipedia.org/facebook-discontinues-messenger-emojis/ |archive-date= Sep 24, 2023 }} Facebook reactions are only partially compatible with standard emoji.{{Cite web|title=👍 Facebook Emoji List — Emojis and Reacts for Facebook|url=https://emojipedia.org/facebook/|access-date=2022-02-07|website=Emojipedia|language=en|quote=Facebook provides animated "emoji" reactions to posts.

Unicode defines variation sequences for many of its emoji to indicate their desired presentation.

{{blockquote |text=Emoji characters can have two main kinds of presentation:

• an emoji presentation, with colorful and perhaps whimsical shapes, even animated
• a text presentation, such as black & white |source=Unicode Technical Report #51: Unicode Emoji}}

Specifying the desired presentation is done by following the base emoji with either U+FE0E VARIATION SELECTOR-15 (VS15) for text or U+FE0F VARIATION SELECTOR-16 (VS16) for emoji-style.{{Cite web|url=https://www.unicode.org/Public/UNIDATA/StandardizedVariants.txt|title=UCD: Standardized Variation Sequences|publisher=Unicode Consortium|access-date=August 17, 2016}} As of version {{Unicode version|version=16}} (2024), Unicode defines presentation sequences for 371 characters.[https://www.unicode.org/Public/16.0.0/ucd/emoji/emoji-variation-sequences.txt Emoji-variation-sequences.txt] However, the Unicode Technical Committee has since determined that unifying colourful emoji characters with textual symbols and dingbats was a "mistake", and resolved to allocate new code points rather than defining new presentation sequences.{{cite web |url=https://www.unicode.org/L2/L2023/23252-legacy-disunification.pdf |title=Proposal to disunify Symbols for Legacy Computing from emoji |first1=Rebecca |last1=Bettencourt |first2=Doug |last2=Ewell |id=UTC L2/23-252}}

{{Main|Emoji modifiers}}

Five symbol modifier characters were added with Unicode 8.0 to provide a range of skin tones for human emoji. These modifiers are called EMOJI MODIFIER FITZPATRICK TYPE-1-2, {{not a typo|-|3}}, {{not a typo|-|4}}, {{not a typo|-|5}}, and {{not a typo|-|6}} (U+1F3FB–U+1F3FF): {{suppress categories|{{lang|zxx-Zsye| 🏻 🏼 🏽 🏾 🏿}}}}. They are based on the Fitzpatrick scale for classifying human skin color. Human emoji that are not followed by one of these five modifiers should be displayed in a generic, non-realistic skin tone, such as bright yellow (■), blue (■), or gray (■). Non-human emoji (like {{unichar|26FD|FUEL PUMP}}) are unaffected by the Fitzpatrick modifiers.{{cite web |url=https://unicode.org/reports/tr51/#Emoji_Modifiers_Display |title=Unicode Technical Standard #51: Unicode Emoji § Expected Emoji Modifiers Display |date=2023-09-05 |first1=Mark |last1=Davis |author-link1=Mark Davis (Unicode) |first2=Ned |last2=Holbrook |institution=Unicode Consortium}} {{Unicode version|prefix=Asof|version=16}}, Fitzpatrick modifiers can be used with 131 human emoji spread across seven blocks: Dingbats, Emoticons, Miscellaneous Symbols, Miscellaneous Symbols and Pictographs, Supplemental Symbols and Pictographs, Symbols and Pictographs Extended-A, and Transport and Map Symbols.

The following table shows both the Unicode characters and the open-source "Twemoji" images, designed by Twitter:

File:Zero Width (Non)Joiner.svg

Implementations may use a zero-width joiner (ZWJ) between multiple emoji to make them behave like a single, unique emoji character. For example, the sequence {{unichar|1F468|MAN}}, {{unichar|200D|ZWJ}}, {{unichar|1F469|WOMAN}}, {{unichar|200D|ZWJ}}, {{unichar|1F467|GIRL}} (👨‍👩‍👧) could be displayed as a single emoji depicting a family with a man, a woman, and a girl if the implementation supports it. Systems that do not support it would ignore the ZWJs, displaying only the three base emoji in order (👨👩👧).

{{anchor|RGI}}Unicode previously maintained a catalog of emoji ZWJ sequences that were supported on at least one commonly available platform. The consortium has since switched to documenting sequences that are recommended for general interchange (RGI). These are clusters that emoji fonts are expected to include as part of the standard.{{Cite web|url=https://www.unicode.org/emoji/charts/emoji-zwj-sequences.html|title=Emoji ZWJ Sequences Catalog|publisher=Unicode Consortium|date=June 14, 2016}}

The ZWJ has also been used to implement platform-specific emoji. For example, in 2016, Microsoft released a series of Ninja Cat emoji for their Windows 10 Anniversary Update.
