Subject Resend: [vfs] vsf2.2.0: non-ascii chars in file name are not handled by createFolder()
Date Thu, 26 Mar 2015 10:52:05 GMT

Is anyone else able to use non-ascii chars in filenames when using VFS 
2.2.0?

As indicated below, the created file has a ? in the resultant name 
rather than the original non-ascii character.

Thanks
