Text with french characters not displaying correctly

Hello,

I am having an issue displaying special characters like in French.
I am using utf8 on both the site and the database and have made several encoding combinations but it is still the same.

For your information, I do not have this issue when using Dreamweaver for example.

Does anyone know the root cause?

Please attached for more details:
