I had to tackle this problem some years ago for VW2.0 - NTFS had just 
come out and had different rules to FAT. Unfortunately it broke some 
deep assumptions about how to verify the acceptability of a filename 
because now the answer depended upon which FS it existed and not just 
on the platform.

The best answer back then was to use the OS api for canonicalising the 
name at whatever time is appropriate. Currently we  don't do that in 
Squeak, relying instead on the implementation of checkname or badChars 
or similar to catch problems. I think the time has come to add an 
optional prim to ask the OS to take a look as well. Several OSs have 
reasonable canonicalisation apis that could be used. Yet another reason 
to get to replacing the crap filesystem code.
