U+04E6 "Ӧ" Cyrillic Capital Letter O with Diaeresis Unicode Character
Unicode Version 17.0
Ӧ
U+04E6 "Ӧ" Cyrillic Capital Letter O with Diaeresis is a modified letter from the Cyrillic script, consisting of a standard Cyrillic "О" with a diaeresis (two dots) placed above it to indicate a specific phonetic value. This character is primarily used in several non-Slavic languages that employ Cyrillic alphabets, such as Khakas, Mari, and Udmurt, where it represents a fronted or palatalized "o" sound, often similar to the German ö or the French eu. Its inclusion in Unicode ensures proper digital representation and text processing for these languages, allowing for accurate transcription and preservation of their distinct vowel systems.
