ISO/TR 11941:1996 is a Koreanromanization system used in ISO. It is not commonly used. One example of its use is in Unicode character names. The standard was withdrawn in December 2013.
This system is used in Unicode character names. For example, the character ᄎ (U+110E) is named "HANGUL CHOSEONG CHIEUCH" (한글 초성 치읓); ㅊ is romanized as "ch." However, the character 차 (U+CC28) is named "HANGUL SYLLABLE CA"; ㅊ is romanized as "c."
