U+00FC. The u with two dots. In German the dots are an umlaut and change the vowel; in Spanish güe and güi they only say that the u is sounded, as in pingüino.
U+00DC. Capital ü. In Turkish, Hungarian, Estonian and Azerbaijani it is a letter of the alphabet, apart from U.
U+00FA. The u with an acute accent: a letter of the Czech, Hungarian and Icelandic alphabets, and in Spanish a u said apart from the vowel beside it, as in baúl.
U+00F9. The u with a grave accent; Unicode's note names French and Italian. In pinyin the grave accent is the fourth tone, the falling one.
U+00FB. The u with a circumflex, the hat. French keeps it in août, once written aoust; in Kurdish û is a long u.
U+016B. The u with a line over it. The line is a macron and marks a long vowel: a letter of Latvian and Lithuanian, and the first tone of u in pinyin.
U+00DA. Capital ú, which the U.S. Option layer also types in one press.
U+00D9. Capital ù.
U+00DB. Capital û.
U+016A. Capital ū.

How it works

A u with 2 dots is ü, capital Ü: Latin small letter u with diaeresis, U+00FC. German calls the dots an umlaut. Turkish, Hungarian and Estonian have the same letter, and so do pinyin and a few Spanish words.

Read the full guide

Umlaut or diaeresis

German sorts its umlaut ü with u and spells it ue where the letter cannot be typed. The diaeresis of Spanish and Catalan looks the same, and Unicode gives the two one character: a u with dots above it, copied here, serves for either.

A capital U with an accent

Of the capitals only Ü has a short Alt code, 154. The others take four digits: Ú is Alt+0218, Ù is Alt+0217 and Û is Alt+0219. Ú is also the one letter here that the U.S. Option layer types in a single press, Option+Shift+;.

  • A u with a tilde is ũ and a u with a circumflex is û. Only û has Alt codes: 150 and 0251.
  • In pinyin ü is written only after l and n. After j, q, x and y the same sound is spelled with a plain u.
  • Where ü is missing from the keyboard, most pinyin input methods take the letter v for it.

How this list was compiled: Names, and the code points they belong to, are checked against UnicodeData.txt, version 18.0.0 (https://www.unicode.org/Public/18.0.0/ucd/UnicodeData.txt), and printed in sentence case. The rows are every character of that file whose decomposition, followed to its end, begins with the letter u or U: 60 letters. Other names of a mark (hat, hacek, long, short, nasal hook), what a mark is used for and the languages a note names follow NamesList.txt of the same version (https://www.unicode.org/Public/18.0.0/ucd/NamesList.txt), as do the headings the letters are filed under; the version a letter was added in is from DerivedAge.txt (https://www.unicode.org/Public/18.0.0/ucd/DerivedAge.txt). Alt codes are from the code page 437 table (https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/PC/CP437.TXT) and the code page 1252 table (https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP1252.TXT); a letter in neither has no Alt code here.
