Fix for incorrectly decoded paths with accents

[aybe]

Hello !

Here's a fix for URLs with accents that were incorrectly saved and consequently triggered an exception.

Example:

800px-David_Guetta_One_Love_Tour_México

was saved to :

800px-David_Guetta_One_Love_Tour_M%C3%A9xico

Now it works it properly.

I'll let you know and PR if I find other issues.

Thank you :D
