smb.conf:

=====
[global]
    mangling method = hash
    unix charset = CP932 (or EUC-JP)
[home]
    writeable = yes
=====

In addition to BUG#190, I found "mangling method = hash" has another
problems to treat multibyte strings.

I will show some samples:
(*) <A> means a Japanese hiragana character (U+3042).

1. a mangled name does not create against a filename more than 8 bytes:

Samba 3.0.0beta1: mangling method = hash, unix charset = EUC-JP
--------
2003/06/26  14:22                    7                 <A><A><A><A><A><A>
--------

Problem1: The length of <A><A><A><A><A><A> is 12byte, but no mangled
name is created. In Samba 2.2.x, a mangled name is created.

This is because "mangling method = hash" in Samba 3.0.0 checks the
number of characters of the string but should check if the byte length
of the string is more than 8 bytes or not.

Problem2:
If we create a file whose name is <A><A><A><A><A><A><A><A><A> ( more
than 9 multibyte chars), then smbd fails in convert_string_allocate()
and calls smb_panic().
