    EUC-KR

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Worldsm.co.kr can be misinterpreted by Google and other search engines. Our service has detected that Korean is used on the page, and neither this language nor any other was claimed in <html> or <meta> tags. Our system also found out that Worldsm.co.kr main page’s claimed encoding is euc-kr. 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.
