    CS

  • Encoding

    WINDOWS-1250

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Mrkev.net can be misinterpreted by Google and other search engines. Unfortunately we cannot identify language used on the page (probably there is a mix of languages, too little text or something else), while the claimed language is Czech. Our system also found out that Mrkev.net main page’s claimed encoding is windows-1250. Changing it to UTF-8 can be a good choice, as this format is commonly used for encoding all over the web and thus their visitors won’t have any troubles with symbol transcription or reading.
