这样的unicode编码，也可以通过另存为解密

或者是

程序代码：
程序代码
<?php
$str = "http://1v1.name";
$str = preg_replace("|&#([0-9]{1,5});|", "\".u2utf82gb(\\1).\"", $str);
$str = "\$str=\"$str\";";

eval($str);
echo $str;

function u2utf82gb($c){
$str="";
if ($c < 0x80) {
$str.=$c;
} else if ($c < 0x800) {
$str.=chr(0xC0 | $c>>6);
$str.=chr(0x80 | $c & 0x3F);
} else if ($c < 0x10000) {
$str.=chr(0xE0 | $c>>12);
$str.=chr(0x80 | $c>>6 & 0x3F);
$str.=chr(0x80 | $c & 0x3F);
} else if ($c < 0x200000) {
$str.=chr(0xF0 | $c>>18);
$str.=chr(0x80 | $c>>12 & 0x3F);
$str.=chr(0x80 | $c>>6 & 0x3F);
$str.=chr(0x80 | $c & 0x3F);
}
return iconv('UTF-8', 'GB2312', $str);
}
?>
