I have the similar problem that it posted with the General Discussion "wms don't support chinese character file name".
If a folder name or file name are including specific character which listed below, web client(HTTP:IPaddress:port) does not display those names properly.(IE8, Firefox3.6 both).
Moreover, the client device of the television (Toshiba REGZA Z8000) doesn't display any list of holders and files, if the file or folder's name includes specific characters which exists in same holder.
The WMS application can show those characters without the problem.
I listeded a part of the character that made the problem.
