U+315A "ㅚ" Hangul Letter Oe Unicode Character
Unicode Version 17.0
ㅚ
U+315A "ㅚ" Hangul Letter Oe is a precomposed jamo, or letter, used in the Korean writing system to represent the vowel sound oe. This character is a combination of the basic Hangul vowels ㅗ (o) and ㅣ (i), reflecting its historical phonetic composition. In modern Korean usage, it appears as a vowel in syllabic blocks and is essential for writing words like 최 (choe) and 외 (oe). Unicode encodes this letter in the Hangul Compatibility Jamo block, where it serves to support legacy text and keyboard input that relies on precomposed forms rather than the more contemporary algorithmically composed syllables.
