    UTF-8

Our service has detected that French is used on the page, and it matches the claimed language. Our system also found out that A4.fr 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.
