U+1E7B "ṻ" Latin Small Letter U with Macron and Diaeresis Unicode Character
U+1E7B "ṻ" Latin Small Letter U with Macron and Diaeresis is a composite glyph used primarily in certain transliteration systems and linguistic notation to represent a specific vowel sound, typically a long close front rounded vowel or a long centralized vowel that requires both a macron (indicating length) and a diaeresis (indicating a separate syllable or a modified pronunciation, such as fronting or unrounding). It appears in some Old English and medieval manuscript transcriptions, as well as in modern scholarly works for phonemic analysis, where it denotes a vowel distinct from its unmarked or singly marked counterparts. This character is part of the Latin Extended Additional block and is encoded as a precomposed form to support accurate text representation and processing in digital environments.
