Unified Hangul Code#IBM1362

Unified Hangul Code is not registered with IANA as a standard to communicate information over the Internet.{{cite web|url=https://www.iana.org/assignments/character-sets |title=Character Sets |website=Iana.org |access-date=2017-01-11}} Alternatives include UTF-8. However, the W3C/WHATWG Encoding Standard used by HTML5 incorporates the Unified Hangul Code extensions into its definition of "EUC-KR".{{citation|url=https://encoding.spec.whatwg.org/#index-euc-kr|title=5. Indexes (§ index EUC-KR)|work=Encoding Standard|publisher=WHATWG |last=van Kesteren |first=Anne |author-link=Anne van Kesteren}}

Microsoft assigns Windows-949 the label "ks_c_5601-1987",{{cite web|url=https://msdn.microsoft.com/en-us/library/system.text.encoding.windowscodepage(v=vs.110).aspx |title=Encoding.WindowsCodePage Property - .NET Framework (current version) |work=MSDN |publisher=Microsoft}}{{citation |url=https://docs.microsoft.com/en-us/windows/desktop/intl/code-page-identifiers |title=Code Page Identifiers |publisher=Microsoft |work=Windows Dev Center|date=7 January 2021 }} which properly applies to KS X 1001 itself (KS C 5601 being the original name of KS X 1001).{{cite web |url=https://opensource.apple.com/source/ICU/ICU-59180.0.1/icuSources/data/mappings/convrtrs.txt.auto.html |quote= [...] using KS C 5601 or related names to denote EUC-KR or windows-949 is very much misleading [...] It's just the name of a 94 x 94 Korean coded character set standard which can be invoked on either GL (with MSB reset) or GR (with MSB set). |author1=IBM |author-link1=IBM |author2=Unicode Consortium |author-link2=Unicode Consortium |work=International Components for Unicode |version=v. 59180.0.1 |title=convrtrs.txt}} The WHATWG treat the label "ks_c_5601-1987" interchangeably with "EUC-KR" with the intent of being "compatible with deployed content".{{cite web | url=https://encoding.spec.whatwg.org/#names-and-labels | title=4.2. Names and labels | publisher=WHATWG | work=Encoding Standard |last=van Kesteren |first=Anne |author-link=Anne van Kesteren}} The Unicode Consortium's "OBSOLETE/EASTASIA" collection of withdrawn mappings included mappings for Unified Hangul Code as "KSC5601.TXT", with the automatically derived mappings for 7-bit KS X 1001 being included as "KSX1001.TXT".{{cite web |url=https://www.unicode.org/Public/MAPPINGS/OBSOLETE/EASTASIA/KSC/KSX1001.TXT |title=KSX1001.TXT: KS X 1001 to Unicode table |author=Jungshik Shin |publisher=Unicode, Inc}}

IBM's code page 949 is another, otherwise unrelated, extension of EUC-KR. International Components for Unicode (ICU) uses "cp949", "949" or "ibm-949" to refer to that IBM code page,{{citation|url=https://ssl.icu-project.org/icu-bin/convexp?conv=cp949|publisher=International Components for Unicode|title=ibm-949_P110-1999 (alias cp949)|work=Converter Explorer}} and "ms949" or "windows-949" (or several variants of "ks_c_5601-1987") to refer to the Windows mapping of UHC. Python, by contrast, recognises "cp949", "949", "ms949" and "uhc" as labels for UHC, and does not include an IBM-949 codec.{{cite web |url=https://docs.python.org/3.7/library/codecs.html#standard-encodings |title=codecs — Codec registry and base classes § Standard Encodings |work=Python 3.7.2 documentation |publisher=Python Software Foundation}} Out of the labels incorporating the code page number, the WHATWG recognise only "windows-949".

{{anchor|IBM1126|IBM1362|IBM1363}}IBM's code page for Unified Hangul Code is called Code page 1363 (IBM-1363), or "Korean MS-Win". It is a combination of SBCS Code page 1126 and DBCS Code page 1362.{{citation|url=https://www-01.ibm.com/software/globalization/ccsid/ccsid1363.html|publisher=IBM|title=Coded character set identifiers - CCSID 1363|work=IBM Globalization|archive-url=https://web.archive.org/web/20141129210404/http://www-01.ibm.com/software/globalization/ccsid/ccsid1363.html|archive-date=2014-11-29|url-status=dead}}{{cite web|title=Code page 1126 information document|archive-url=https://web.archive.org/web/20170116144609/https://www-01.ibm.com/software/globalization/cp/cp01126.html|archive-date=2017-01-16|url=https://www-01.ibm.com/software/globalization/cp/cp01126.html}}{{cite web|title=CCSID 1126 information document|archive-url=https://web.archive.org/web/20160327100212/http://www-01.ibm.com/software/globalization/ccsid/ccsid1126.html|archive-date=2016-03-27|url=http://www-01.ibm.com/software/globalization/ccsid/ccsid1126.html}}{{cite web|title=Code page 1362 information document|archive-url=https://web.archive.org/web/20160317081150/http://www-01.ibm.com/software/globalization/cp/cp01362.html|archive-date=2016-03-17|url=https://www-01.ibm.com/software/globalization/cp/cp01362.html}}{{cite web|title=CCSID 1362 information document|archive-url=https://web.archive.org/web/20160327040022/http://www-01.ibm.com/software/globalization/ccsid/ccsid1362.html|archive-date=2016-03-27|url=http://www-01.ibm.com/software/globalization/ccsid/ccsid1362.html}} It differs in having a single byte mapping of 0x5C to the Won sign (U+20A9);{{citation|url=http://demo.icu-project.org/icu-bin/convexp?conv=ibm-1363|publisher=International Components for Unicode|title=ibm-1363|work=Converter Explorer}}{{Citation|title=Code Page CPGID 01126 (pdf)|url=https://public.dhe.ibm.com/software/globalization/gcoc/attachments/CP01126.pdf|publisher=IBM}}{{Citation|title=Code Page CPGID 01126 (txt)|url=https://public.dhe.ibm.com/software/globalization/gcoc/attachments/CP01126.txt|publisher=IBM}} Windows maps 0x5C to U+005C (the Unicode code point for the backslash) as in ASCII,{{citation|url=http://demo.icu-project.org/icu-bin/convexp?conv=windows-949-2000|publisher=International Components for Unicode|title=windows-949-2000|work=Converter Explorer}} although fonts often still render it as a Won sign.{{citation | title=When is a backslash not a backslash? | date=2005-09-17 | author=Kaplan, Michael S. | url=http://archives.miloush.net/michkap/archive/2005/09/17/469941.html | work=Sorting it all out}} Unicode mapping of the wave dash (0xA1AD) also differs, with the IBM mapping favouring U+301C,{{cite web|url=https://ssl.icu-project.org/icu-bin/convexp?conv=ibm-1363_P110-1997&b=A1&s=ALL#layout|title=ibm-1363_P110-1997 (lead byte A1)|work=ICU Demonstration - Converter Explorer|publisher=International Components for Unicode}} while the Microsoft mapping favours U+223C (Tilde Operator).{{cite web|url=https://ssl.icu-project.org/icu-bin/convexp?conv=windows-949-2000&b=A1&s=ALL#layout|title=windows-949-2000 (lead byte A1)|work=ICU Demonstration - Converter Explorer|publisher=International Components for Unicode}} The IBM mapping for UHC is available as "ibm-1363" in ICU, whereas the ICU "windows-949" codec is referred to as IBM-1261 in some ICU source code comments.See, for reference, [https://opensource.apple.com/source/ICU/ICU-59180.0.1/icuSources/common/ucnv_lmb.cpp.auto.html ucnv_lmb.cpp] (Brendan Murray, Jim Snyder-Grant), where the lead byte 0x11 is commented as referring to "Korean: ibm-1261" after the definition of ULMBCS_GRP_KO, but it is mapped to the "windows-949" ICU codec in the OptGroupByteToCPName array later in the file.

Following is the single-byte portion of the code page as defined by IBM. Similarly to Code page 437, the control code bytes may be used as control codes or graphical codes depending on context—the graphical codes are shown below. Microsoft uses ASCII mappings for all ASCII bytes, although the backslash may still be rendered as a won sign.
