请问js里如何实现utf8编码转换成汉字呢？

类如%CD%F8%D2%B3%CB%D1%CB%F7的编码，转换成汉字。希望各位帮忙。！

这是我收藏的一段代码，我自己没有验证过代码，你可以参考一下：

function URLEncode(strURL)
{
var strSpecialUrl = " <>\"#%{}|^~[]`'&?+";
var strEncode="";
var i, j, chUrl, iCode, iCodeBin, num;
var tempBin;
var leadingzeros;

strURL+="";
for (i=0; i<strURL.length; i++) {
chUrl = strURL.charAt(i);
iCode = chUrl.charCodeAt(0);
if (iCode<=parseInt("0x7F")) {
if (strSpecialUrl.indexOf(chUrl)!=-1) {
//chUrl is a special character that needs to be Url encoded
strEncode+="%"+iCode.toString(16).toUpperCase();
} else {
//otherwise chrUrl is normal
strEncode+=chUrl;
}
} else {
leadingzeros="";
iCodeBin=iCode.toString(2)
if (iCode<=parseInt(0x7FF)) {
//glyph is represented by two chars

//check leading zeros on iCodeBin (should be 11 digits)
for (j=11; j>iCodeBin.length; j--) leadingzeros+="0";
iCodeBin=leadingzeros+iCodeBin

tempBin="110"+iCodeBin.substr(0,5);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(5,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
} else {
if (iCode<=parseInt(0xFFFF)) {
//glyph is represented by three chars

//check leading zeros on iCodeBin (should be 16 digits)
for (j=16; j>iCodeBin.length; j--) leadingzeros+="0";
iCodeBin=leadingzeros+iCodeBin

tempBin="1110"+iCodeBin.substr(0,4);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(4,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(10,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
} else {
if (iCode<=parseInt(0x1FFFFF)) {
//glyph is represented by four chars

//check leading zeros on iCodeBin (should be 21 digits)
for (j=21; j>iCodeBin.length; j--) leadingzeros+="0";
iCodeBin=leadingzeros+iCodeBin

tempBin="11110"+iCodeBin.substr(0,3);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(3,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(9,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(15,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
} else {
if (iCode<=parseInt(0x3FFFFFF)) {
//glyph is represented by five chars

//check leading zeros on iCodeBin (should be 26 digits)
for (j=26; j>iCodeBin.length; j--) leadingzeros+="0";
iCodeBin=leadingzeros+iCodeBin

tempBin="111110"+iCodeBin.substr(0,2);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(2,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(8,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(14,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(20,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
} else {
if (iCode<=parseInt(0x7FFFFFFF)) {
//glyph is represented by six chars

//check leading zeros on iCodeBin (should be 31 digits)
for (j=31; j>iCodeBin.length; j--) leadingzeros+="0";
iCodeBin=leadingzeros+iCodeBin

tempBin="1111110"+iCodeBin.substr(0,1);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(1,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(7,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(13,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(19,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
tempBin="10"+iCodeBin.substr(25,6);
strEncode+="%"+parseInt(tempBin,2).toString(16).toUpperCase()
}
}
}
}
}
}
}
return strEncode;
}

不知道楼主得到这段“%CD%F8%D2%B3%CB%D1%CB%F7”的页面的编码是什么，即以下？？？？处的内容

<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=？？？？">

知道楼主这串编码是怎么得到的了：

以下页页，用ansi编码存盘，浏览，在输入框里敲回车就出来了。
<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>New Page 1</title>
</head>
<body>
<form >
<input name=a value="网页搜索">
</form>
</body>

</html>
