U+3171 "ㅱ" Hangul Letter Kapyeounmieum Unicode Character
Unicode Version 17.0
ㅱ
U+3171 "ㅱ" Hangul Letter Kapyeounmieum is a unique and obsolete symbol from the history of the Korean writing system. It represents a "labialized" or weakly bilabial version of the consonant "ㅁ" (mieum, /m/), historically used in the now-uncommon "kapyeoun" series of Hangul letters that indicated softer, aspirated, or altered pronunciations. This character was primarily employed in early Korean phonological studies and transcriptions but is no longer part of modern standard Hangul, making it a rare relic preserved in Unicode for scholarly and historical representation.
