U+04EA "Ӫ" Cyrillic Capital Letter Barred O with Diaeresis Unicode Character
Unicode Version 17.0
Ӫ
U+04EA "Ӫ" Cyrillic Capital Letter Barred O with Diaeresis is a modified Cyrillic letter used primarily in the Khanty language, where it represents a specific mid-central vowel sound that occurs in certain dialects. It combines the Cyrillic barred O (with a horizontal stroke through its center) with a diaeresis, or umlaut, placed above the character to indicate a further fronted or centralized articulation. This letter is distinct from the more common Cyrillic O and appears in the Unicode standard as part of the Cyrillic Extended A block, supporting the accurate transcription of Indigenous Siberian languages. Its lowercase counterpart is U+04EB "ӫ", and its use remains limited to specialized linguistic and typographic contexts.
