首先进行声明
use Encode;
gbk转uft-8:
$line = encode(“utf-8″,decode(“gbk”,$line));

$line = encode_utf8(decode(“gbk”,$line));
utf-8转gbk:
$line = encode(“gbk”, decode(“utf8″, $line));
uft-8转gb2312:
$line = encode(“gb2312″, decode(“utf8″, $line));

perl中对URL地址进行编码

URL中如果有中文的字符,要先对其进行编码才能进行下一步的处理。

* 用替换方法进行编码:

Url encode:对 n 不转码
perl -pe ‘s/([^w-.@])/$1 eq “n” ? “n”:sprintf(“%%%2.2x”,ord($1))/eg’ keywords.list

* 用替换方法进行解码:

Url Decode:
perl -pe ‘s/%(..)/pack(“c”, hex($1))/eg’ keywords.list

* 用URI::URL模块进行编码

use URI::URL;
my $str = “http://www.google.com/lxmxn’s blog&b=Hello,perl”;
my $url = URI::URL->new( $str );
print $url;

* 用URI::Escape模块进行编码

use URI::Escape;
my $str=’北极神话’;
print uri_escape($str);

#result:%B1%B1%BC%AB%C9%F1%BB%B0
