U+04E7 "ӧ" Cyrillic Small Letter O with Diaeresis Unicode Character
Unicode Version 17.0
ӧ
U+04E7 "ӧ" Cyrillic Small Letter O with Diaeresis is a variant of the Cyrillic letter O, distinguished by the addition of two dots (a diaeresis) placed above it, which indicates that the vowel is pronounced separately or with a specific phonetic quality, such as in the Udmurt and Khanty languages where it represents a fronted or palatalized sound. It is part of the Cyrillic Extended-A block and is used primarily in the orthographies of certain minority languages within Russia, where it serves to differentiate this sound from the standard Cyrillic O. The uppercase counterpart is U+04E6 "Ӧ", and the character is encoded for digital text to preserve the authentic representation of these languages in modern communication.
