Unicode Version 17.0
ㆌ
U+318C "ㆌ" Hangul Letter Yu-I is a specialized Hangul jamo representing a digraph that combines the vowel sounds of 'yu' and 'i', and it is primarily used in the historical or linguistic transcription of the Korean language, particularly in older documents or academic contexts to denote this specific diphthong. It belongs to the CJK Compatibility block, which contains characters intended for compatibility with earlier encoding standards, and as a result it appears less frequently in modern everyday Korean text, which typically employs standard modern Hangul syllables.
