  • Encoding

    UTF-8

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Kvc.ac.th can be misinterpreted by Google and other search engines. Our service has detected that Thai is used on the page, and it does not match the claimed English language. Our system also found out that Kvc.ac.th 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.
