U+3178 "ㅸ" Hangul Letter Kapyeounpieup Unicode Character

U+3178 "ㅸ" Hangul Letter Kapyeounpieup is a historical Jamo which was used in Early Modern Korean orthography to represent a now obsolete bilabial fricative sound, typically romanized as a "b" or "v" between vowels. It is a composite letter formed by adding a short vertical stroke to the bottom of the basic Hangul consonant ㅂ (pieup), and it appears in the Hangul Compatibility Jamo block primarily for legacy and scholarly text encoding. This character is no longer used in standard modern Korean, but it remains essential for accurately representing Middle and Early Modern Korean documents, linguistic analysis, and digital preservation of historical texts.
