U+111A "ᄚ" Hangul Choseong Rieul-Hieuh Unicode Character

U+111A "ᄚ" Hangul Choseong Rieul-Hieuh is a leading consonant cluster used in the Korean writing system, representing the combination of the sounds for "rieul" (an 'r' or 'l' sound) and "hieuh" (an 'h' sound) at the beginning of a syllable. It is part of the Hangul Jamo block in Unicode, which encodes the individual letters that make up Korean syllables, and is typically invisible to modern readers as it appears in archaic or historical texts rather than contemporary Korean. This jamo was used in older forms of Hangul to denote a specific phonetic sequence that has since fallen out of common usage, preserved primarily for linguistic study or digital representation of classical Korean documents.
