U+C624 "오" Hangul Syllable O Unicode Character
Unicode Version 17.0
오
U+C624 "오" Hangul Syllable O is a precomposed syllable representing the Korean vowel sound “o” as in the English word “oh.” It is formed from the Hangul letter ㅇ (ieung, a placeholder consonant that is silent in initial position) and the vowel ㅗ (o), and it is the standard way to write the syllable 오. This character is part of the Hangul Syllables block in Unicode, which contains precomposed syllables that allow for efficient text processing of the Korean writing system. In modern Korean, 오 can function as an independent word meaning “five” or as an interjection expressing surprise or acknowledgment, much like “oh” in English.
