U+014D "ō" Latin Small Letter O with Macron Unicode Character
Unicode Version 17.0
ō
U+014D "ō" Latin Small Letter O with Macron is a grapheme consisting of the base Latin letter 'o' combined with a macron diacritic, a horizontal line placed above it to indicate a long vowel sound, as seen in the romanization of Japanese (for example, "Tōkyō") and in languages like Māori and Latvian. It is encoded in the Latin Extended-A block of the Unicode Standard, serving to distinguish phonemic length in written text where the macron modifies the pronunciation of the vowel.
