U+1ED7 "ỗ" Latin Small Letter O with Circumflex and Tilde Unicode Character
Unicode Version 17.0
ỗ
U+1ED7 "ỗ" Latin Small Letter O with Circumflex and Tilde is a precomposed Latin letter used primarily in the Vietnamese alphabet, where it represents the vowel sound "o" with a circumflex accent indicating a high, falling-rising tone and a tilde denoting a creaky or breathy voice quality in the mid-rising tone. This character combines the base letter "o" with both diacritics to form a distinct grapheme essential for accurately writing Vietnamese words such as "cỗ" meaning "offering" or "bỗng" meaning "suddenly". It is part of the Latin Extended Additional block in Unicode and is employed in modern text processing and digital communication to preserve the tonal distinctions that are fundamental to the Vietnamese language.
