U+1ECC "Ọ" Latin Capital Letter O with Dot Below Unicode Character
Unicode Version 17.0
Ọ
U+1ECC "Ọ" Latin Capital Letter O with Dot Below is a composite glyph used primarily in the orthographies of several African languages, including Yoruba, Igbo, and Vietnamese, where the dot diacritic beneath the letter O signals a distinct phonemic value, typically representing a more closed or lowered vowel sound compared to the plain O. In practical usage, this character is essential for accurate transcription and literacy in these languages, allowing writers to distinguish words that would otherwise be homographs. It appears in both uppercase and lowercase forms, with the lowercase counterpart being U+1ECD "ọ", and is supported by most modern Unicode-compliant fonts and text rendering systems.
