Unified Hangul Code (UHC,[2] Korean: 통합형 한글 코드[3], translit. Tonghabhyeong Hangeul Kodeu), also known under Microsoft Windows as Code Page 949 (Windows-949), is the Microsoft Windows code page for the Korean language. It is an extension of Wansung Code (KS C 5601:1987, encoded as EUC-KR) to include all 11172 Hangul syllables present in Johab (KS C 5601:1992 annex 3).[2] This corresponds to the pre-composed syllables available in Unicode 2.0 and later.

IBM's code page for Unified Hangul Code is called Code page 1363 (IBM-1363), or "Korean MS-Win". It is a combination of Code page 1126 and Code page 1362.[4] It differs in having a single byte mapping of 0x5C to the Won sign (U+20A9);[5] Windows maps 0x5C to U+005C (the Unicode code point for the backslash) as in ASCII,[6] although fonts often still render it as a Won sign.[7] IBM's code page 949 is a different extension of EUC-KR.

The code page is not registered with IANA as a standard to communicate information over the Internet.[8] 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.[1]
