U+1156 "ᅖ" Hangul Choseong Phieuph-Pieup Unicode Character

U+1156 "ᅖ" Hangul Choseong Phieuph-Pieup is a special initial consonant cluster used in the Korean writing system, representing a digraph that combines the sounds of the bilabial aspirated stop "ph" (from ᅖ Phieuph) and the bilabial unaspirated stop "p" (from ᅗ Pieup). This character is categorized as a leading jamo, meaning it appears solely as the first consonant of a Hangul syllable block, and it derives from Middle Korean phonology where such clusters were more common in transcribing Chinese loanwords or dialectal pronunciations. While it is not used in modern standard Korean, it remains encoded in Unicode for historical and academic purposes, preserving the script’s full typographic and phonetic heritage.
