Faceted search not working on a french store

[Vanquiched]

Hello, 

I'm setting up a prestashop store, which is working fine so far. 

I ran into a problem where i have a faceted search to sort my categories pages by categories. On the english versiob of the store, it works like a charm. On my french version, i have a very strange bug: it does not work.

I dig into the details, and it seems like the english version appends this to the URL when you click on a category : &q=Categories-10mm which looks good. The french version, tho, tries to append and encoded version of "Catégories-10mm", so the accent causes a problem.

 

You have any idea how i can solve this ? 

 

Thanks a lot.
