How to type Ü ü — U with umlaut / diaeresis

Type it on our keyboard

Open the field already filled with ü — type or click more, then copy. No install, works offline:

Codes

Reference	ü	Ü
Unicode	U+00FC	U+00DC
HTML entity	`ü`	`Ü`
CSS escape	`\00FC`	`\00DC`
macOS — Unicode Hex Input	`⌥` 00FC	`⌥` 00DC
Windows — Word	00FC `Alt + X`	00DC `Alt + X`

macOS hex input needs the “Unicode Hex Input” source enabled (System Settings → Keyboard). The Windows Alt + X trick works in Word and Outlook; elsewhere use the panel below.

On a Mac

Quick combo: press ⌥U then U.
Press and hold the u key — an accent menu pops up; pick ü.
Character Viewer: ⌃⌘Space, search “u with umlaut / diaeresis”, double-click it.

On Windows

Emoji & symbols: Win + ., switch to symbols, find ü.
Character Map (search it in the Start menu) → find ü → Copy.

With PolyType installed

If you run the PolyType app or browser extension, type the base letter then the diacritic — no layout switch (the directive accents the letter immediately before it):

u;umlaut␣

The instant cycle ;;u also works (repeat to cycle variants). This inline syntax needs PolyType running; without it, use a method above.
