Social Networking :: Twitter API - Space Character Gets Changed To 2520 When Tweet Is Liked

I have a [URL]...... When I click on Like tweet then it is changed into [URL] ...... Except Tweet Like i have no problem. In others it is changed into [URL] ..... So i don't have any problem. For Twitter Like I am using this Code:

<a href="https://twitter.com/share" class="twitter-share-button">Tweet</a>  
<script language="javascript" type="text/javascript">
!function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (!d.getElementById(id)) {
js = d.createElement(s);
js.id = id; js.src = "//platform.twitter.com/widgets.js";
fjs.parentNode.insertBefore(js, fjs); } }
(document, "script", "twitter-wjs");</script>
 
I have done URL Routing:

System.Web.Routing.RouteTable.Routes.MapPageRoute("View Catalogues", "Colors/View Catalogues", "~/ViewCatalogues.aspx");
