Thank you for the suggestion, but as far as I can see prename is not UTF-8-
aware. Is that true?

I'm right now studying 

if I enter

myuser@mysytem:~/path-name-of-unicode-files$ rename -n 's/\x{202A}//' *

I get no output although x{202A} is definitely the first char in the filename.
This definitely needs more than a cursory view into perl - exactly what I 
wanted to avoid.
Maybe I better post in a perl mailinglist. Only I'm afraid that I'll get 
nothing but RTFM! and "do your own homework!" - they maybe right ...
