It's a persistently annoying, if very minor issue that in English the word 'umlaut' is used for the diaresis. The "Umlaut" in German is actually the whole letter of Ä, Ö, and Ü, and they are separate letters, not just 'a, o, or u with an "umlaut"'.
I think I did that deliberately after the new forum platform was introduced because I didn't want to be tagged in anything. I can't remember why now-just being a cunt probably...
It’s hard to @ you with the umlaut over the u!
