KS X 1001
South Korean character set standard to represent hangul and hanja characters on a computer
KS X 1001, "Code for Information Interchange (Hangul and Hanja)", formerly called KS C 5601, is a South Korean coded character set standard to represent Hangul and Hanja characters on a computer.
KS X 1001 is encoded by the most common legacy (pre-Unicode) character encodings for Korean, including EUC-KR and Microsoft's Unified Hangul Code (UHC). It contains Korean Hangul syllables, CJK ideographs (Hanja), Greek, Cyrillic, Japanese (Hiragana and Katakana) and some other characters.
KS X 1001 is arranged as a 94×94 table, following the structure of 2-byte code words in ISO 2022 and EUC. Therefore, its code points are pairs of integers 1–94. However, some encodings (UHC and Johab), in addition to providing codes for every code point, provide additional codes for characters otherwise representable only as code point sequences.
History
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.
The present, double-byte, Wansung (완성; Wanseong; lit. 'precomposing') character set was standardised by the third edition of KS C 5601, which was published in 1986.

Why this record matters
The phrase “south Korean character set standard to represent hangul and hanja characters on a computer” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 22, 2026. The linked authority identifier is Q489423. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1001, 2022, 1987 and 1992.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
