U+0231 "ȱ" Latin Small Letter O with Dot Above and Macron Unicode Character

U+0231 "ȱ" Latin Small Letter O with Dot Above and Macron is a specialized grapheme used primarily in certain Latin-based orthographies, most notably in the Livonian language for representing a specific long vowel sound. This character is formed by combining a standard lowercase "o" with a combining dot above and a combining macron, indicating both vowel length and a distinctive articulation. It belongs to the Latin Extended-B block of the Unicode standard and is a relatively rare character, not found in common text but essential for accurate digital representation of Livonian and other academic or linguistic transcriptions. Its inclusion in Unicode ensures that such precise phonetic distinctions can be preserved in electronic documents, supporting the documentation and revitalization of endangered languages.
