Share: with german Umlaut (special Character) path

I’m using UCS 4.4-7 and I created some samba shares on a Read-Only-DC.
The shares are displayed properly in UCS and if I try to list all shares on a client (Windows or Mac) it does not display the share which path is containing a umlaut, e.g. “Büro” in the foldername of the full path. It is not a real option to rename the folder of the path, the name of the share is already set to Buero.

Is this a known issue and how can I come around this to get the folder shared?

Thanks in advance

fyi: could not find an other solution than renaming the folder itself to a name without German Umlaut-character
