[Samba] UTF8 not working

[Dexter Filmore]

Slackware 11.0, Samba 3.0.23c

After two years absence from Samba I need to use it again. 
A week ago I switched my entire network to UTF8 which works fine locally, 
works fine via NFS.

Now mounting the SMB shares german Umlauts are broken.
"Für alle ein Segen.mp3"
becomes
"F?r alle ein Segen.mp3"

Server config:

[global]
        display charset = UTF-8
        workgroup = CITADEL
        server string = Samba %v
        log file = /var/log/samba/log.%m
        max log size = 10240
        valid users = dexter
        admin users = dexter
        read list = dexter
        write list = dexter
        printer admin = dexter
        hosts allow = 192.168.0.0/24

[media]
        path = /mnt/data/media
        read only = No

The fstab entry on the client:

//xerxes/media /mnt/xerxes/smb/media cifs credentials=<foo>,rw,users 0 0


So - why no UTF-8 chars?
