U+315F "ㅟ" Hangul Letter Wi Unicode Character

Unicode Version 17.0

U+315F "ㅟ" Hangul Letter Wi is a precomposed Hangul jamo representing the vowel sound "wi," which is a combination of the basic vowels "u" and "i" in the Korean writing system. This character belongs to the Hangul Compatibility Jamo block, a range of Unicode that provides legacy compatibility for older Korean text encoding systems. While the modern standard for writing Hangul typically uses the combined forms of leading consonants, medial vowels, and trailing consonants, this specific "ㅟ" jamo is still found in historical documents, certain dictionary entries, and specialized linguistic contexts. Its encoding ensures that digital text can correctly represent and preserve this specific vowel symbol, which is pronounced with the lips rounded for the "u" part and then spreading for the "i" part, a distinct sound in the Korean phonological system.
