How do I know the encoding of a website?
One way to check this is to use the W3C Markup Validation Service. The validator usually detects the character encoding from the HTTP headers and information in the document. If the validator fails to detect the encoding, it can be selected on the validator result page via the ‘Encoding’ pulldown menu (example).
