U+315D "ㅝ" Hangul Letter Weo Unicode Character

U+315D "ㅝ" Hangul Letter Weo is a precomposed vowel letter from the Hangul script used in the Korean language, representing the diphthong sound "weo" which is formed by combining the basic vowels ㅜ (u) and ㅓ (eo). This character is part of the Hangul Compatibility Jamo block in Unicode, historically encoded for compatibility with older Korean character sets, and it serves as a standalone syllable-initial vowel component in Hangul orthography. In modern usage, it is often encountered in legacy text encoding or when inputting Korean without using modern Unicode normalization that might decompose it into separate jamo, ensuring consistent representation of the Korean writing system across different platforms and applications.
