Strictly speaking it is the filesystem which defines which characters are legal, not the operating system. This means that a drive shared between *nix and Windows (using, say, Samba) can have an interesting effect on file naming. Also remember that NTFS filenames can contain Unicode characters.

Take a look at the .pm for File::Basename (which should be in your base release).
