|Alias(es)||KS C 5657|
|Language(s)||Intended to be used alongside KS X 1001 for Korean support. Does not substantially support any language on its own.|
|Standard||KS X 1002|
|Current status||Unihan source. Not usually encoded directly.|
|Classification||Supplementary charset, ISO 2022, DBCS, CJK encoding|
|Other related encoding(s)||JIS X 0212|
Unlike KS X 1001, KS X 1002 is not encoded in any legacy encoding. Even in 1994, it was known as "a standard that no one implemented."
Characters in KS X 1002 are arranged in a 94×94 grid (as in ISO/IEC 2022), and the two-byte code point of each character is expressed in the haeng-yeol form, which specifies a row (haeng 행) and the position of the character within the row (cell, yeol 열).
The rows (numbered from 1 to 94) contain characters as follows:
- 01–07: Latin letters with diacritics (613 characters)
- 08–10: Greek letters with diacritics (273 characters)
- 11–13: miscellaneous symbols (275 characters)
- 14: compound jamo and hangul syllables without an initial consonant (27 characters)
- 16–36: modern hangul syllables (1,930 characters)
- 37–54: archaic hangul syllables (1,675 characters)
- 55–85: hanja (2,856 characters)
The rows 15 and 86–94 are unassigned.
Impact on Unicode
In Unicode 1.1, the characters at U+3D2E–U+44B7 were from rows 16–36 of KS X 1002. However, they were deleted and superseded by the new Hangul Syllables block (U+AC00–U+D7AF) in Unicode 2.0.
