Im testing BackWPup and found that files with international characters in name are not backed up. I'm getting an error saying that the files are not readable.
In the log the offending character is displayed as +?
In my language letters like áéýúíó ÁÉÝÚÍÓ ÞÆÐÖ þæðö are used so we get a lot of filenames like áfangaskýrsla.pdf
Any solution to this problem?
