French characters and SEF advance

Hi,

I'm facing a problem with some french characters, I tried to use the replace function but couldn't find the solution. I'm having such URL www.cassedu.com/v3/guide/bars/billards/l...ligator/details.html where the righ URL should be www.cassedu.com/v3/guide/bars/billards/l-alligator/details.html
This one points to a page but some others generate 404
Any idea about how to replace it ?
Thanks in advance
Thomas

Special chars like single quotes are url encoded. You can except it from encode or have it replaced by some other character, but not by hyphen if it's used as word separator.

You can also use short URLs without accents or manual alias for that link.
