Language and Encoding

  • Language Detected

    FR

  • Language Claimed

    FR

  • Encoding

    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 D-pro.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.

For example, adding the following code snippet into HTML <head> tag will help to represent this web page correctly in social networks:
