Unicode Version 17.0
Ṹ
U+1E78 "Ṹ" Latin Capital Letter U with Tilde and Acute is a composite glyph representing the letter U modified by both a tilde and an acute accent, specifically used in certain linguistic transcriptions and orthographies for African languages such as Yoruba and some dialects of Vietnamese. This character combines the nasalization indicated by the tilde with the high tone or stress indicated by the acute, allowing precise phonetic representation where tone and nasality occur simultaneously. It is part of the Latin Extended Additional block in Unicode and is typically encoded through precomposed form or as a sequence of the base letter U followed by combining diacritical marks.
