U+1ED6 "Ỗ" Latin Capital Letter O with Circumflex and Tilde Unicode Character

U+1ED6 "Ỗ" Latin Capital Letter O with Circumflex and Tilde is a precomposed glyph used primarily in the Vietnamese alphabet to represent a specific vowel sound characterized by a falling then rising tone combined with the clipped, glide-like quality indicated by the circumflex. It is part of the Latin Extended Additional block and is composed of a base Latin capital letter O combined with both a circumflex accent (^) and a tilde (~) diacritic stacked above it. In Vietnamese, this character appears in words that require the hỏi or ngã tone on the ô vowel sound, helping to distinguish meaning between words that would otherwise be homographic. This character is typically used in written Vietnamese language contexts and is supported by most modern Unicode compliant fonts.
