U+04E9 "ө" Cyrillic Small Letter Barred O Unicode Character

Unicode Version 17.0

ө

U+04E9 "ө" Cyrillic Small Letter Barred O is a distinct glyph used in several Cyrillic alphabets, most notably in the Bashkir, Kalmyk, Kazakh, Kyrgyz, Mongolian, and Tuvan languages, where it represents a close-mid central rounded vowel sound, similar to the 'u' in the English word "put" but with the tongue positioned higher and more centralized. This character is visually defined by a horizontal bar or stroke drawn through the center of the standard Cyrillic letter O, which distinguishes it from the similar looking Latin letter theta or the lowercase omicron. It functions as an independent letter in its respective alphabets and should not be confused with the homoglyphic Latin letter "o" with a bar, as its usage is specific to Cyrillic script orthographies where it fills a phonetic gap not covered by the regular O or other vowel letters.
