Ü

Ü (Latin Capital Letter U With Diaeresis, U+00DC) is an uppercase Latin letter visually characterized by a capital 'U' with two horizontal dots, known as a diaeresis or umlaut, positioned above it. This character plays a crucial role in several European and Turkic languages. In German, it's known as "U-Umlaut," representing a distinct front rounded vowel sound, which can be transcribed as "UE" when the umlaut is unavailable. Beyond German, Ü is essential in languages like Hungarian, Estonian, Turkish, and Azerbaijani, where it denotes specific vowel qualities. While the two dots aesthetically resemble a diaeresis (which indicates separate pronunciation of vowels, as in French "Saül"), in many contexts, especially in German, they function as an umlaut, signifying a historical vowel shift. Its common lowercase counterpart is ü (U+00FC).
