Decode \u003d and other \u code

In a JSON feed Google Base converts this URL:
http://www.realtybargains.com/guest/PropertyDetails.rb?PID=2789602&GB=search&rs=google

Into this:
http://www.realtybargains.com/guest/PropertyDetails.rb?PID\u003d2789602\u0026GB\u003dsearch\u0026rs\u003dgoogle

Using only JavaScript, how can I convert it back?

I don't want to simply replace this:
        \u003d
with this:
        =

Because there could be other characters in other links that are also encoded.  I would like to figure out the significance of this
      \u003d

and properly decode the JSON code they send me.

Thanks!

Here is a continuation of one I did earlier this week

you want ncr2utf(str)

<script>
 function d2h(d) {return d.toString(16).toUpperCase();}
function h2d(h) {return parseInt(h,16);} 
 
 function ncr2utf(str) {
   var chars = str.replace(/\&\#/g,'').split(';')
   for (var i=0;i<chars.length;i++) if (chars[i]) chars[i]="\\u"+d2h(parseInt(chars[i]));
   return chars.join(''); 
 }
 
 function utf2ncr(str) {
   var chars = str.split('\\u')
   for (var i=0;i<chars.length;i++) {
   	  alert(i+':'+chars[i])
   	  if (chars[i]) chars[i]="&#"+h2d(chars[i])+';';
   }
   return chars.join(''); 
 }
 
 var str = "&#49548;&#44060;"
 document.write(str.replace(/&/g,'&amp;')+':['+str+']:['+ncr2utf(str)+']:['+utf2ncr(ncr2utf(str))+']') //  should become \uC18C\uAC1C.
 </script>
