U+01DF "ǟ" Latin Small Letter A with Diaeresis and Macron Unicode Character

U+01DF "ǟ" Latin Small Letter A with Diaeresis and Macron is a composite glyph used primarily in the transliteration and scholarly transcription of certain languages, such as Livonian and occasionally in the romanization of other languages where vowel length and umlaut distinctions are necessary. It combines a standard lowercase 'a' with a diaeresis, indicating a fronted or modified vowel quality, and a macron above it, marking the vowel as long in duration. This character ensures precise phonetic representation in linguistic texts, particularly for Baltic and Finno-Ugric language studies, where both vowel length and quality are phonemic. It is encoded as a precomposed letter in the Latin Extended-A block of Unicode, allowing for consistent digital display and data exchange without the need for combining diacritical marks.
