怎样把沈阳这样的unicode源码转换成简体的汉字？

 1<script>   
 2a = "&#x6c88;&#x9633;"   
 3b = a.replace(/&#x/gi,"")   
 4b= b.split(";")   
 5for(i = 0;i<b.length-1;i++)   
 6{   
 7alert(String.fromCharCode(parseInt(b[i],16)))   
 8  
 9}   
10</script>

1<script language="javascript" runat="server">   
2a = "&#x6c88;&#x9633;"   
3b = a.replace(/&#x/gi,"");   
4b= b.split(";");   
5for(i = 0;i<b.length-1;i++)   
6{   
7Response.write(String.fromCharCode(parseInt(b[i],16)));   
8}   
9</script>
