Yes.  All multibyte character sets in common use are a superset of
ASCII.  Any that aren't a proper superset of ASCII have more issues than 
just Samba stripping out metacharacters.  So if you just remove the set 
of ASCII characters that are known to be illegal, it should not pose any 
problems for national charsets.
