Issue managing folder named with Chinese (or asian language) chars in Media Manager

Hi Team,

I would like to report an issue with the Media Manger in Easy Blog 3.9.16263 (latest).

1) I cannot create folder name with Chinese character (Linux) via the Media manger in EasyBlog; the folder turn out to be a number eg: 208, typed chinese characters all gone.
2) The folder created in this situation cannot be deleted via EasyBlog (eg: 208), guess some "invalid character" issue with the folder name which cannot be rendered in EasyBlog.
3) I can add a "dash" before the chinese characters, folder will be created and rendered correctly

If this is system constraint from EasyBlog, I suggest to add some code to "block out" creating folder with "invalid character" or "Chinese character", else, maybe add a number before the real folder name will help? or there are some problem gotta be fixed with EasyBlog for "unicode / asian language" handling for folder's name?

I need to delete the folder via console shell from the server side, finally.

Please advise it can be fixed or limited. Thanks.

Best regards,
Alfred
