I forgot to include one warning about excl:*locale*: due to Motif  
using the libc's locale definition, excl:*locale* must be bound to a  
locale that both allegro cl and the libc understand. From the  
behavior you reported below, it looks like the libc doesn't  
understand that C.UTF-8 means it should use utf-8 encoded characters.  
(that's why you get the error: allegro cl expects a utf-8 encoded  
string, but gets a latin-1 one).

I tested with de_AT.UTF-8 on debian gnu/linux. If you have utf-8  
locale definitions for your current locale (I'm assuming that's  
de_DE), I suggest you use that and append .UTF-8 to get de_DE.UTF-8.

I'll try to come up with a test for acl&libc locale compatibility,  
but for now, I hope the above will work for you.
