That's strange. The forum software is encoded with UTF-8 and so are the language files. UTF-8 contains all chars of rather all actual used letter systems of this planet including french accentuated letters. Did you open and save the file with UTF-8-charset (without BOM)?

Well, the problem existed from the installation, so the first time I modified and saved the lang file was when I tried to fix this problem. But don't worry, it works perfectly now with [default] added to the file...

Thanks a lot for your time, MLF is exactly what I was searching for

A last question : do you think of adding a clearer way to report a content that's causing trouble? For instance, with a button "Report this message". Right now -correct me if I'm wrong- the only way to report a problematic message is to click to Contact in the footer? The reason why I'm asking this is because I won't moderate the forum beforehand so I would feel more comfortable with such a feature that enables customers to complain easily in case of problem.
