U+1EDC "Ờ" Latin Capital Letter O with Horn and Grave Unicode Character
Unicode Version 17.0
Ờ
U+1EDC "Ờ" Latin Capital Letter O with Horn and Grave is used primarily in the Vietnamese alphabet to represent a specific tonal variant of the vowel sound /ɔ/. The horn diacritic attached to the base letter O indicates that the vowel is pronounced with rounded lips and a slightly different tongue position, while the grave accent marks the low falling tone known as "huyền" in Vietnamese phonology. This character appears in words such as "chợ" meaning market, and it is part of the Vietnamese extended Latin script, which relies on a combination of base letters and diacritical marks to accurately represent the language's six distinct tones and vowel distinctions.
