hijacking an 4 year old thread with the topic Atutor is maybe not the best idea to get support on another problem with characters.
I suggest the next time you open a new thread, that will highly improve the chance to get answers for your prob.
From my small knowledge point about character issues you should look at 3 parts:
1) character encoding from your server (utf8 ?)
2) character encoding from your database / mysql (utf8 ?? --> in most cases here is the problem with wrong characters) and also the collation
3) character encoding from your webbrowser.
Ideally they should all be the same and proven to handle french character set.
