Just as, indeed, in German, the word "Umlaut" refers to the whole letter and not only to the two dots above it. The German alphabet is similar to the Swedish one and looks like this:

ä, ö, and ü are distinct letters and form a third class of letter, "Umlaute", besides vowels ("Vokale") and consonants ("Konsonanten").

Bet you always wanted to know this. :)

I didn't want to know, or at least there was no innate desire, but I'm glad to have been informed.
