İ, or i, called dotted I or i-dot, is a letter used in the Latin-script alphabets of Azerbaijani, Crimean Tatar, Gagauz, Kazakh, Tatar, and Turkish. It commonly represents the close front unrounded vowel {{IPA|/i/}} except in Kazakh in which it additionally represents the voiced palatal approximant {{IPA|/j/}} and the diphthongs {{IPA|/ɪj/}} and {{IPA|/əj/}}. All languages that use it also use its dotless counterpart I, but not the basic Latin letter I.
In computing
{{Main|Dotted and dotless I in computing}}The dotted I is encoded into Unicode with the code point U+0130 (U+0069 for the lowercase letter) as part of the Latin Extended-A block.{{Cite web |title=Latin Extended-A |url=http://www.unicode.org/charts/PDF/U0100.pdf |archive-url=https://web.archive.org/web/20010603005154/http://www.unicode.org/charts/PDF/U0100.pdf |archive-date=2001-06-03 |access-date=2023-11-21 |website=Unicode Consortium}}{{charmap

= Issues =
The dotted and dotless I characters have caused issues in computing. Languages like Turkish have four variants of the letter I (opposed to two in English). This causes problems when, instead of the original mapping of i to I, Turkish maps i to the new İ, and ı to I, frequently breaking software logic.{{Cite web |last=Texin |first=Tex |title=Internationalization for Turkish: Dotted and Dotless Letter "I" |url=http://www.i18nguy.com/unicode/turkish-i18n.html |access-date=2023-11-21 |website=www.i18nguy.com}}
Usage in other languages
Both the dotted and dotless I can be used in transcriptions of Rusyn to allow distinguishing between the letters Ы and И, which would otherwise be both transcribed as "y", despite representing different phonemes. Under such transcription the dotted İ would represent the Cyrillic І, and the dotless I would represent either Ы or И, with the other being represented by "Y".{{cn|date=February 2025}}
