U+022D "ȭ" Latin Small Letter O with Tilde and Macron Unicode Character
Unicode Version 17.0
ȭ
U+022D "ȭ" Latin Small Letter O with Tilde and Macron is a composite glyph that combines a Latin small letter O with two diacritical marks, a tilde and a macron, stacked above it. This character is used primarily in certain phonetic transcription systems and in some orthographies for minority languages, where it represents a specific vowel sound, often a long or nasalized version of the letter O. It falls within the Latin Extended-B block of Unicode, a range that covers various additional Latin characters not included in the basic Latin set. While not common in mainstream languages, "ȭ" serves as a precise typographic tool for linguists and scholars documenting speech sounds.
