U+315C "ㅜ" Hangul Letter U Unicode Character
Unicode Version 17.0
ㅜ
U+315C "ㅜ" Hangul Letter U is a vowel symbol from the Korean writing system of Hangul, specifically representing the sound /u/. It is classified as a "Hangul Compatibility Jamo," part of a block designed for compatibility with pre-existing Korean character encoding standards. Visually, the glyph resembles a horizontal line with a short vertical stroke extending downward from its left end, and it plays a fundamental role in forming Korean syllables by combining with initial consonants. This character is distinct from the modern "Hangul Jamo" block's equivalent, as it is intended for use in legacy text and certain typographic contexts.
