It consists of a total of 7,649 characters.
[1] 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).
KS X 1002 is one of the sources of the CJK Unified Ideographs block in Unicode.
[3][4] In Unicode 1.1, the characters at U+3D2E–U+44B7 were from rows 16–36 of KS X 1002.
[5][6][7][8] However, they were deleted and superseded by the new Hangul Syllables block (U+AC00–U+D7AF) in Unicode 2.0.
