U+01D5 "Ǖ" Latin Capital Letter U with Diaeresis and Macron Unicode Character

U+01D5 "Ǖ" Latin Capital Letter U with Diaeresis and Macron is a composite glyph used primarily in Latin-based orthographies and scholarly transcription systems to represent a specific phonetic or diacritic combination. It consists of a capital U base letter combined with a diaeresis (two dots above) and a macron (a horizontal line above) placed over the diaeresis, indicating a long vowel sound with diaeresis. This character is particularly employed in the writing of certain languages, such as in the romanization of Old English or in some Central European and Baltic language notations where precise vowel length and quality marking are required. It is encoded as a single precomposed character in Unicode to provide a standard representation for such typographic needs, avoiding the need for combining marks in digital text.
