U+3179 "ㅹ" Hangul Letter Kapyeounssangpieup Unicode Character

U+3179 "ㅹ" Hangul Letter Kapyeounssangpieup is a rarely used historical jamo that represents a double (ssang) and aspirated (kapyeoun) variant of the bieup consonant, specifically a fortis labial sound found in older forms of the Korean writing system. It is composed of two pieup (ㅂ) characters combined with the kapyeoun diacritic, indicating a stronger, tensed articulation. This character is part of the Hangul Compatibility Jamo block and is primarily of interest to linguists and scholars studying Middle Korean phonology or archaic orthographic conventions, as it is no longer used in modern Korean.
