smbclient is someone elses headache.

Please note the difference between smbfs and smbmount. This problem is in
smbfs, not in smbmount.

What exactly do you mean by 8bit characters? unsigned char is a 8bit value
... are you talking about 0x00-0x1f or 0x80-0xff? A "strange" character
set would be using parts of 0x80-0xff (unless unicode, which it is on
NTFS but not on FAT).

Could you find the binary value of these characters? Or tell me how to
create a file with a non-working name.

That character has a real value. which? smbfs fails here when it tries to
find more info about the file, using the filename.

(This problem wouldn't appear if smbfs was a little more clever and used
 the fileinfo it reads at once, most likely a great speedup for ls. Or if 
 it was even more clever and spoke unicode with the NT.)
