Is there a command line tool or online service that can convert javascript unicode notation code to utf-8?
E.g. I got this json code, but it is hard to edit in common text editor.
{"name":"leon zhang","city":"\u4e0a\u6d77"}
I want to convert it to:
{"name":"leon zhang","city":"上海"}
You use the below javascript function to convert unicode to utf-8
function encode_utf8( s ){
return unescape( encodeURIComponent( s ) );
}( '\u4e0a\u6d77' )
You can also try it out in firebug console. It works.

document.all.content.focus();
document.all.content.select();
}
function clearContent(){
document.all.content.value = "";
document.all.content.focus();
}
</script>

<table width="600" border="1" cellspacing="0" cellpadding="0" align="center" style="text-align:center;">
<tr>
<td>Input what you want to convert：</td>
<td><input type="text" name="content" id="content" size="50"/></td>
</tr>
<tr>
<td colspan="2">
<input type="button" name="encoding" value="Start Conversion" onclick="encodeGB2312()"/>
<input type="button" name="clear" value=" Cancel" onclick="clearContent();"/></td>
</tr>
</table>
</body>

This is a sample of convert utf-8 to unicode, do it in turn.
