[Samba] What's wrong with accentued filenames in 2.2.3a????

[Rickos]

  Hello,

i read many many faq, docs, mailing lists archive, however smbclient 
command don't work with filenames/directories of a share(under win98) 
composed of accentued characters (i'm french, did you notice it with my 
english level :) ).
my conf is:
-OS: linux 2.4.17 with RH 7.1
-kernel option:
CONFIG_SMB_NLS_DEFAULT=y
CONFIG_SMB_NLS_REMOTE="cp850" (cp437 tried)
CONFIG_NLS_DEFAULT="iso8859-1"
CONFIG_NLS_CODEPAGE_XX=y
CONFIG_NLS_ISO8859_1=m
CONFIG_NLS_ISO8859_15=m (for euro symbol)

-smb.conf:
client code page = 850
character set = ISO8859-15

--with a smbmount all works fine:
#smbmount -t smbfs <service> <mnt-point>
and 2 nls_* modules are used:
#lsmod:
nls_cp850 3616 1
nls_iso8859-1 2880 1
nls_iso8859-15 3392 0 (unused)
and
#cd <mnt-point>/test-a`e' -> ok

--BUT with smbclient:
#smbclient <service> -U <user> -s <conf>
smb :\cd test-a`e'
cd \test-a`e'\: ERRDOS - ERRbadpath (Directory invalid.)

What's wrong, is it a bug???
