KS X 1001
KS X 1001 (Korean Graphic Character Set for Information Interchange) is a South Korean coded character set standard to represent hangul and hanja characters on a computer. It is arranged as 94×94 table (similarly to 2-byte code words in ISO 2022 and EUC), therefore its code points are pairs of integers 1–94. KS X 1001 contains Korean Hangul syllables, CJK ideographs (Hanja), Greek, Cyrillic, Japanese (Hiragana and Katakana) and some other characters.
This standard was previously known as KS C 5601. There have been several revisions of this standard. For example, there were revisions in 1987, 1992, 1998 and 2002. Several computer operating systems encode various versions of this standard several ways. Not all of them encode the standard the same way, like replacing the typical backslash at byte 0x5C with the won currency sign (₩). Some operating systems extend this standard in other non-uniform ways. Possible encoding schemes of KS X 1001 are: EUC-KR, windows-949 (superset of EUC-KR), ISO-2022-KR and JOHAB. However, the latter two encodings are rarely used.
