Here’s a little php function which returns the file’s character encoding from a meta tag of a webpage.

$content = file_get_contents("http://www.simra.ch");
echo getEncoding( $content );

function getEncoding( $content ) {
preg_match( '@<meta\s+http-equiv="Content-Type"\s+content="([\w/]+)(;\s+charset=([^\s"]+))?@i',$content, $matches );
return $matches[3];
}
