Hello, I’m french too and am looking for the exact same thing : special characters in categories’ names not appearing in URLs.
Presently if I have a category named “présentement”, the slug for it is “présentement” instead of “presentement” (whereas other characters like the single quotes, for example, are removed, as wanted), how to fix it ?
I found it. Just have to put this line in the config file :
RemovePathAccents = true
