Encode::BOCU1::XS - Perl extension for encoding / decoding BOCU-1 string. Works as part of Encode.pm


NAME

Encode::BOCU1::XS - Perl extension for encoding / decoding BOCU-1 string. Works as part of Encode.pm


SYNOPSIS

use Encode::BOCU1::XS;

$string = 'UTF-8 text to convert...' Encode::from_to($string,'utf8','bocu1');

$string = 'BOCU-1 data to convert...' Encode::from_to($string,'bocu1','shiftjis');


DESCRIPTION

BOCU-1 is a MIME-compatible application of the Binary Ordered Compression for Unicode [BOCU] base algorithm developed and patented by IBM.

Encode::BOCU1::XS enables to convert any encoding systems supported by Encode.pm from/to BOCU-1 through UTF-8. It uses a lot less CPU than Encode::BOCU1, the original pure-perl module.
