Our service has detected that Japanese is used on the page, and it does not match the claimed Chinese language. Our system also found out that C2j.jp 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.
