Unicode Version 17.0
ㆈ
U+3188 "ㆈ" Hangul Letter Yo-Yae is a specialized letter from the Hangul Compatibility Jamo block that represents a composite vowel sound in the Korean writing system. It is formed by combining elements of the vowel 'yo' (ㅛ) with 'yae' (ㅒ) to denote a phonetic glide or a historical diphthong that was once used in Middle Korean or in certain dialectal transcriptions, but it is not a standard letter in modern South Korean orthography. Today, this character is primarily encountered in academic linguistic texts or historical digital archives when representing older Korean phonology.
