CharsetDetector - A Charset Detector, optimized for EastAsia charset and website content


        use CharsetDetector;
        use CharsetDetector qw(detect detect1);
        #simple use it
        $charset = CharsetDetector::detect($octets);
        #with length limit
        $charset = CharsetDetector::detect($octets,$max_len);
        #don't consider html head charset as a factor to detect charset
        $charset = CharsetDetector::detect1($octets);
        $charset = CharsetDetector::detect1($octets,$max_len);

Basic Function ^

detect - detect charset

        $charset = CharsetDetector::detect($octets);
        $charset = CharsetDetector::detect($octets,$max_len);

detect1 - detect only by binary

detect charset don't consider html head charset as a factor to detect charset by DEFAULT, detetor will consider html header (e.g. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> ) as a factor to detect charset, if you don't want detetor to consider html header as a factor, use detect1 instead of detect

        $charset = CharsetDetector::detect1($octets);
        $charset = CharsetDetector::detect1($octets,$max_len);

Return Value

if $octets is null return '' if $octets is '' return 'iso-8859-1' else return charset name
