Issue exporting deck with comments in a foreign language

```
1. Create a deck. Name it and add in the comment part "éà". Try to export 
the deck under a text format.

There is an error message: "An error occured while saving."

ARDB 3.0.1 under Windows 7.

Seems like a lack of support of utf-8 or of the codepages.
