Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Prefix.io can be misinterpreted by Google and other search engines.

Our system also found out that Prefix.io 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.
