U+01EA "Ǫ" Latin Capital Letter O with Ogonek Unicode Character
Unicode Version 17.0
Ǫ
U+01EA "Ǫ" Latin Capital Letter O with Ogonek is a variant of the letter O that includes a diacritical mark called an ogonek, a small hook attached to the bottom right of the letter. This character is used primarily in the writing systems of several Indigenous languages of North America, such as Navajo and Western Apache, where it represents a nasalized vowel sound, similar to the "o" in the French word "bon" but with a distinct phonetic quality. It also appears in some European languages like Lithuanian and Polish for historical or phonological purposes, though in those contexts it typically occurs as a lowercase form or in specific orthographic traditions.
