Unfortunately we cannot identify language used on the page (probably there is a mix of languages, too little text or something else), while the claimed language is French. Our system also found out that main page’s claimed encoding is utf-8. Use of this encoding format is the best practice as the main page visitors from all over the world won’t have any issues with symbol transcription.
