What's HTML character code 8203?

What does the character code (HTML) ​? I found it in one of my jQuery scripts and wondered what it was..

Thanks.

Edit:

Here is the script it was in (it was added to the end, found it in Firebug)

<script src="http://code.jquery.com/jquery-latest.js" type="text/javascript"></script>
<script type="text/javascript">
var $jnyh = jQuery.noConflict();


$jnyh(function() {
    $jnyh("#title-nyh").click(function() {
      $jnyh(".show-hide-nyh").slideDown("slow");
    }, function() {        
      if(!$jnyh(this).data('pinned'))
        $jnyh(".show-hide-nyh").slideUp("slow");
    });
    $jnyh("#title-nyh").click(function() {
    $jnyh(this).parent().toggleClass("title-btm-brdr");
       $jnyh(this).toggleClass("chev-up-result");
      var pin = $jnyh(this).data('pinned');
      $jnyh(this).data('pinned', !pin);
      if(pin) $jnyh(".show-hide-nyh").slideUp("slow");      
    });
});​&#8203;
</script>
