Big5 及 UTF-8 编码的转换方式有两种 (请先安装 Encode::compat 模组):

方式一

use Encode::compat;
use Encode qw(from_to);

my $string = "中文";

#Big5 转 UTF-8
from_to($string, 'big5', 'utf8');
print "$string\n";

#UTF-8 转 Big5
from_to($string, 'utf8', 'big5');
print "$string\n";

方式二

use Encode::compat;
use Encode qw(encode decode);

my $string = "中文";

#Big5 转 UTF-8
my $utf8 = encode('utf8', decode('big5', $string));
print "$utf8\n";

my $big5 = encode('big5', decode('utf8', $utf8));
print "$big5\n";
