i don t know how to put those dots with my keyboard =(.
Wikipedia to the rescue:
In Microsoft Windows, one can hold alt while pressing 0220 or 154 on the numeric keypad (when Num Lock is on) as a shortcut to Ü and hold alt while pressing 0252 or 129 as a shortcut to ü.
Some local keyboard layouts, especially German and Swiss German layouts, feature a separate key for the letter 'Ü'. On Swiss French layout the 'Ü' can be entered by typing 'É' while holding down the shift key. On US International layout Windows users can access the acute accent letter 'Ü' by holding down the "AltGR" key whilst typing the 'Y' key on the keyboard.
In Mac OS, one can hold option (alt) while pressing u to obtain the dots and then u again (or any other desired vowel that shall receive the dots) to place it under the dots.
The Unicode code point for ü is U+00FC. (252) Ü is U+00DC. (220)The last means that in Linux-based operative systems, like Ubuntu which I use, you can hold down Ctrl and Shift and type UFC and it gives you ü.
But my Norwegian keyboard is so wisely equipped that I have a separate key which puts the diacritics on not just ä, ë, ï, ö, ü and ÿ.....
Funny how a word can change its meaning without the umlaut.
.....but also on ñ, so that I can make the equally vital distinction between
ano and
año!
It's also totally accepted to write words with umlauts, like Führer, as Fuehrer. Because the dots in the umlaut did actually originally represent a small superscripted e, in the same way as the tilde in ñ originally is a small n.
