Hi Matthias,

unfortunately there also is letter a with combining dieretic - and it is used by MacOS
The mac seems to prefer decomposed characters in other contexts as well, so in my
everyday job I used to have fun with product catalogues from a few companies.
Depending on the computer used for adding / editing a productthe relevant field could be
iso-latin-1, utf8 normal, or utf8 decomposed

I usually try to avoid whitespace and accented charactersin filenames, to be able to use ssh and scp
without much hassle, but I am not the user in this case.

Now, if I look at a music collection (stored as folders with mp3 files for the tracks), I would really prefer
"Einstürzende Neubauten" over Einstuerzende_Neubauten

Wolfgang
