This is an interesing question. Does this work when accessing a Samba
share containing the same CP852 characters ?

What changed for 2.0.6 is that smbclient now assumes that
the filenames being returned are in the codepage format
that is specified in "client code page =" in the smb.conf,
and will convert, using the dos_to_unix() function, to
the character set used by the UNIX box (as specified in
the "character set =" parameter).

Now, can you please test doing this against a share exported
from a Samba 2.0.6. server. If that works correctly (the 
filenames are being seen ok), but doesn't work when the
ls is done against a Windows PC (and also the version of
Windows being used as a fileserver will be very usefull
here) then we need to look more carefully at the code page
of the filenames being returned by a Windows file server.

Thanks for your help on this, please get back to me asap
as we are trying to decide upon the fixes that should go into
Samba 2.0.7 at the moment.
