Small Php/Mysql charset problem

I'm using a script for one of my websites that was in english. I put the translation to french and all the special characters went crazy.
I tried to change the charset and almost everything and I could not find the source of this problem.
I know that it must not be a big deal.
So I'm looking for someone to fix it for me. Pm me your offer.
Thank you.

Just change your database type to UTF-8.
