U+0227 "ȧ" Latin Small Letter A with Dot Above Unicode Character
Unicode Version 17.0
ȧ
U+0227 "ȧ" Latin Small Letter A with Dot Above is a modified Latin letter used primarily in historical or phonetic transcription contexts, where the dot above the letter indicates a specific phonetic feature, such as a palatalized or centralized pronunciation, though it is relatively rare in modern standard languages. It belongs to the Latin Extended-A block of Unicode and is distinct from similar-looking characters like the combining dot above or precomposed letters in other alphabets. In some orthographies, it may appear as part of medieval manuscripts or academic notations for transcribing older forms of Slavic or Baltic languages, but it is not commonly found in contemporary everyday text.
