NAME

Encode::Detect::CJK - A Charset Detector, optimized for EastAsia charset and website content

SYNOPSIS

use Encode::Detect::CJK; #just use
  
use Encode::Detect::CJK qw(detect); #use and export function 

#simple use it
my $charset=CharsetDetector::detect($octets);

#use it with advanced option
my $charset = CharsetDetector::detect($octets,$max_len,$is_consider_html_head_charset);
#return the charset of binary string $octets
#$max_len if $octets 's size is big, will make detect slow, sometimes you need specify $max_len for 
#       detect,null is for DEFAULT(unlimit max_len)
#$is_consider_html_header_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, set $is_consider_html_header_charset to "" or 0

Basic Function

detect - detect the charset of string

$charset=CharsetDetector::detect($octets,$max_len,$is_consider_html_head_charset);
$charset=CharsetDetector::detect($octets,$max_len);#CharsetDetector::detect($octets,$max_len,1);
$charset=CharsetDetector::detect($octets);#same as CharsetDetector::detect($octets,undef);

Param $octets - input binary string

input binary string

Param $max_len - max length for charset detector

if $octets 's size is big, will make detect slow, sometimes you need specify $max_len for detect,null is for DEFAULT(unlimit max_len) DEFAULT is unlimit

Param $is_consider_html_head_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, set $is_consider_html_header_charset to `` or 0

Return Value $charset

if $octets is null return if $octets is return 'iso-8859-1'
