Cant delete File in File Manager: Data supplied is not accepted, following characters are not allowed

Dears,

It is not possible to Rename or even Delete a file with a not allowed name in the File Manager.

I understand this can be done by FTP, but I think it should be possible as well by the file manager.

Current Version : 2.3 Build 1

Best regards!
