Description Clemens Schwaighofer 2004-11-09 18:36:18 UTC
I have a server running debian/testing with samba 3.0.7-debian. My Client is
Gentoo/stable with 3.0.7 debian.

my local LANG is en_US.UTF-8

I have several japanese filenames on the server (they are utf-8 there of
course). If I mount the share with

mount.cifs //fileserver/share share/ -o user=me

then I see just questionmarks.

If I try to mount it it with

mount.cifs //fileserver/share share/ -o user=me,ipcharset=utf8

then I see a long, very long string of questionmarks, blocks, and some very
strange kanji instead of the ver simple japanese filename.

The filename is correctly viewed on the fileserver with the same shell
(gnome-terminal, terminal encoding set to utf-8).

I have no other utf-8 characters like umlauts etc to test, but at least with
japaense its not working ...

Should be fixed by changes to fs/cifs/file.c and the new file fs/cifs/readdir.c 
which created a new cifs readdir routine which handles utf8 variable length 
characters much better (strings were getting overwritten in some asian 
languages before).  Should be fixed in 2.6.10 or later kernels (patches 
available for some earlier kernels on the project page). 
note that the syntax is iocharset (not ipcharset) but that should not be 
necessary in any case when the server supports unicode (as Samba 3 and Windows
