U+01D7 "Ǘ" Latin Capital Letter U with Diaeresis and Acute is a composite glyph that represents the letter U modified by two diacritical marks: a diaeresis (two dots) above the U and an acute accent placed above the diaeresis. This character is used in certain romanization systems for languages such as Mandarin Chinese, where it denotes a high rising tone on the close front rounded vowel /y/, as well as in some orthographies of European languages to distinguish specific vowel qualities or tones. It is part of the Latin Extended-A block and is typically employed in linguistic transcription or formal writing where precise phonetic or tonal notation is required.
