Deja-Dup Restore does not work

[Sascha]

The Backup with DejaDup is executed without any error.
Then I wanted to restore a file

1. The Special characters are not recognized correctly so "dell´anima.doc" is shown as "dell
2. If i execute the restore nevertheless i get a FOLDER ! "dell�anima.doc (codifica non valida)" instead of a doc file.

Where is my data ?????

So the restore function with special characters for me as normal user is completly broken.
People are not aware that they can not redo their backup. -> Risk of complete data loss
This is why i consider this as a major bug. This should never happen with a offical release of a backup software !
