U+1ED3 "ồ" Latin Small Letter O with Circumflex and Grave Unicode Character
Unicode Version 17.0
ồ
U+1ED3 "ồ" Latin Small Letter O with Circumflex and Grave is a composite glyph used primarily in the Vietnamese language, where it represents the sound of the letter "o" with a circumflex accent indicating a higher, more closed vowel quality, combined with a grave accent to denote a low-falling tone. This character is part of the Latin Extended Additional block and is constructed by combining the base letter "o" with a circumflex diacritic (^) and a grave diacritic (`), allowing for precise phonetic transcription in Vietnamese orthography. It is commonly found in words such as "hồ" (meaning lake or pond) and plays an essential role in distinguishing meaning through tonal variation.
