U+1E7A "Ṻ" Latin Capital Letter U with Macron and Diaeresis Unicode Character

U+1E7A "Ṻ" Latin Capital Letter U with Macron and Diaeresis is a composite glyph used in the written form of certain languages where both a macron (a horizontal line above the letter indicating a long vowel) and a diaeresis (two dots, used to show that the vowel is pronounced separately from a preceding vowel, or to denote a different vowel quality) are applied to the capital letter U. This character is primarily utilized in linguistic or academic transcriptions, particularly for transliterating languages such as Sanskrit or other ancient or modern texts that require precise vowel length and pronunciation markers. It is part of the Latin Extended Additional block in Unicode, serving to represent a specific phonetic or orthographic distinction that neither a simple U, U with macron, nor U with diaeresis alone can convey.
