  • Encoding

    WINDOWS-1251

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Nikol-n.com 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 Bulgarian. Our system also found out that Nikol-n.com main page’s claimed encoding is windows-1251. 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.
