Ȫ

Ȫ (Latin Capital Letter O With Diaeresis And Macron, U+022A) is a distinctive Unicode character representing an uppercase 'O' adorned with both a diaeresis (two dots) and a macron (a horizontal line) above it. This unique combination of diacritics is not found in common Western European languages but plays a crucial role in specialized linguistic transcription and the orthography of certain minority languages. Most notably, it is used in the Livonian language, a critically endangered Finnic language spoken in Latvia, where the lowercase ȫ and uppercase Ȫ denote a specific long, front-rounded open-mid vowel sound. Its presence in the Latin Extended-B block highlights Unicode's commitment to supporting the diverse written forms of the world's languages, even those with complex phonetic representations, ensuring their digital preservation and accessibility.
