[Samba] incomplete smbmount smbfs Win98SE iso8859-1 translation in kernel 2.4.18

[Ian! D. Allen [NCFreeNet]]

I'm getting only partial iso8859-1 translation from an smbfs mount from
my Win98SE machine.  The smbfs mounted file system shows most lower-case
accented characters fine; but, it substitutes underscores for most of
the upper-case accented characters (and a few lower-case ones too):

# uname -a
Linux elm 2.4.18-8.1mdkian3 #7 Sat Aug 17 15:19:44 EDT 2002 i686 unknown
(Mandrake 8.2 Linux with all Mandrake updates [including kernel] applied.)

# mount -r -t smbfs -o iocharset=iso8859-1,codepage=cp850 //win/D /mnt/d

# cat /proc/mounts | grep /mnt/d

# lsmod | grep nls
nls_cp850               3584   1  (autoclean)

The first underscore (between c cedilla and e acute accent) is supposed
to be ã (small a with tilde).

The next two sets of five underscores correspond to upper-case accented
vowels, first with circumflexes and second with grave accents.

Naturally, I can't access any of the files that have had underscores
substituted; because, when Unix sends the file name with underscores
back to Win98SE it has no file by that name.

Why am I getting only partial translation to latin-1?
Pointers to more man pages graciously accepted...
