Tag duplication with accentuate characters

[Pititjo]

When a multiple tasks use a tag with accentuate characters (éèà...) the tag is duplicated.

Way to reproduce the bug :
- create a task and apply a tag with an accentuate character
- create an other task and apply the same tag
- close gtg
When gtg is reopen, the tag is twice in the tag panel. If you create three tasks, the tag is three time in the tag panel.

The previous comment is not related. It has to do with the fact that tagname are saved in unicode. So "é" becomes '\xc3\xa9' which is not nice and a complicated issue :-(
