U+1157 "ᅗ" Hangul Choseong Kapyeounphieuph Unicode Character

U+1157 "ᅗ" Hangul Choseong Kapyeounphieuph is a now obsolete letter from the Korean Hangul alphabet, historically used in the early Middle Korean period to represent a specific consonant sound. This character denotes an aspirated bilabial stop, pronounced like a "p" sound with a strong puff of air. Unlike modern Hangul, which uses a systematic combination of basic and derived letters, the Kapyeounphieuph is part of a separate class of "archaic" or "obsolete" initial consonants that appeared in early documents. It was eventually phased out as the Korean writing system standardized, and today it is primarily of interest for historical linguistics, textual scholarship, and digital encoding to preserve ancient Korean manuscripts.
