U+00FC "ü" Latin Small Letter U with Diaeresis Unicode Character
Unicode Version 17.0
ü
U+00FC "ü" Latin Small Letter U with Diaeresis is a lowercase vowel used in several languages, most notably in German where it represents a front rounded vowel resulting from umlaut, as well as in Spanish, French, and others to indicate that the 'u' should be pronounced separately from a preceding vowel. In the Latin alphabet, it is formed by placing two dots, known as a diaeresis or umlaut, above the letter 'u'. This character is distinct from the digraph 'ue' that sometimes replaces it in German when the umlaut is unavailable, and it holds a specific code point in the Unicode standard for consistent digital representation across systems.
