    WINDOWS-1252

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Laphysique.net can be misinterpreted by Google and other search engines. Our service has detected that French is used on the page, and it matches the claimed language. Our system also found out that Laphysique.net main page’s claimed encoding is windows-1252. 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.
