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);

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