U00DCU00FC

U00DCU00FC refers to two Unicode code points: U+00DC, Latin capital letter U with diaeresis, and U+00FC, Latin small letter U with diaeresis. When written together as Ü and ü, they form the letters used with umlauts or diaereses in several languages. The string U00DCU00FC is a hex-coded way to represent these two characters in some technical contexts.

In language usage, Ü/ü denotes a front rounded vowel [y] in languages that use umlauts. In German, it appears in words such as Über or München and distinguishes pronunciation from U/u. In Turkish and Azerbaijani, Ü/ü is an official letter of the Latin alphabet and represents the same or a closely related sound. It also occurs in Estonian and other languages via loanwords and proper names. The two letters are distinct letters from U and u and carry their own phonological and orthographic significance.

Encoding and representation: U+00DC and U+00FC reside in the Unicode Latin-1 Supplement block. In UTF-8, Ü is encoded as 0xC3 0x9C and ü as 0xC3 0xBC. In HTML, they can be written as Ü and ü, or numerically as Ü and ü. They are widely supported in modern text systems, fonts, and input methods, reflecting their role in many European languages and in internationalized text.
