U+0168 "Ũ" Latin Capital Letter U with Tilde is a precomposed glyph used in several languages to represent a vowel sound where the standard Latin letter U is modified by a tilde diacritic, indicating a nasalized pronunciation. This character is found in the orthographies of languages such as Vietnamese, where it appears as part of the tonal system for the vowel "u" with a tilde representing the ngã tone, and in certain African languages like Umbundu and some dialects of Guarani.
