UTF-8 Unicode Ansi 汉字GB2321几种编码转换程序
今天搞sxna,遇到了编码转换的难题，找了一个多小时，历尽千辛万苦，总算总结了如下的汉字转换为各种UTF-8 Unicode Ansi编码的程序．不敢独享，特此奉献给各位编程爱好者！
<script language="JAVASCRIPT" runat="server">
var ss;
var dd;
ss=decodeURIComponent("%E6%B1%89%E5%AD%97");
dd=encodeURIComponent("汉字");
</script>
符合GOOGLE的UTF编码
<p>
汉字 经过encodeURIComponent变成
<%=dd%>
</p>
<p>
%E6%B1%89%E5%AD%97经过decodeURIComponent变成
<%=ss%>
</p>

<script language="vbscript" runat="server">

符合BAIDU的UTF-8编码
