ISO/TR 11941:1996 (Information and documentation — Transliteration of Korean script into Latin characters) is a Korean romanization system used in International Organization for Standardization (ISO). It is mainly used in character names in Unicode and ISO/IEC 10646. The technical report was withdrawn in December 2013.
Transliteration rules
Apostrophe The apostrophe (') is used for resolving ambiguity. It is used in the following cases.
Both Method I and Method II: When ㅇ appears at the initial position of a non-initial syllable of a polysyllabic word (e.g. 앉아라 anc'ara/anj'ara) When ㄲ, ㄸ, ㅃ, ㅉ, or ㅆ appears at the initial position of a non-initial syllable of a polysyllabic word (e.g. 아까 a'kka/a'gga) Method I only: When ㅋ, ㅌ, ㅍ, or ㅊ appears at the initial position of a non-initial syllable of a polysyllabic word (e.g. 애타다 ae'thata) In fact, the above rules are always applied; they are applied even when there is no ambiguity (e.g. 아이 a'i, 흰떡 hyin'tteok/hyin'ddeog).
In character names in Unicode and ISO/IEC 10646 In Unicode and ISO/IEC 10646, both Method I and Method II are used for character names.
Method I: characters in the Hangul Jamo and Hangul Compatibility Jamo blocks (e.g. U+1103 ᄃ HANGUL CHOSEONG TIKEUT (디귿), U+3148 ㅈ HANGUL LETTER CIEUC (지읒)) Method II: characters in the Hangul Syllables block (e.g. U+AF43 꽃 HANGUL SYLLABLE GGOC) As the apostrophe is not allowed in character names, it is always omitted. For example, 옛이응 is yes'i'eung in ISO/TR 11941, but YESIEUNG in Unicode and ISO/IEC 10646 (e.g. U+114C ᅌ HANGUL CHOSEONG YESIEUNG).
