U+112D "ᄭ" Hangul Choseong Sios-Kiyeok Unicode Character

U+112D "ᄭ" Hangul Choseong Sios-Kiyeok is a precomposed consonant cluster used in the initial (choseong) position of a Korean syllable block, representing a combination of the sounds for ᄉ (sios) and ᄀ (kiyeok), effectively producing a "sk" or "sg" sound at the start of a syllable. This character is part of the Hangul Jamo Extended-A block, which was encoded to support historical or obsolete Korean phonology. While not used in modern standard Korean, it appears in older texts or linguistic transcriptions to denote a tensed or complex onset. As a single Unicode code point, it facilitates faithful digital representation of such clusters without needing separate jamo composition.
