title: How does one escape the # sign in a Url pattern in UrlMappings.groovy?
body: <p>In order to maintain the current set of Urls in a project, I have to be able to use the <strong>#</strong> (pound sign) in the Url.  For some reason the pound sign does not appear to work normally in this project for UrlMappings.groovy.</p>
  
  <p>Is there a special <strong>escape-sequence</strong> that must be used when placing # signs in <strong>UrlMappings.groovy</strong>?</p>
  
  <p>Am I missing some reason why one cannot use pound signs at all?</p>
  
  <p>In the following URL Mapping example, the browser goes to the correct page, but the pageName variable is null:</p>
  
  <pre><code>"/test/${urlName}#/overview"(controller:'test', action:'overview') {
      pageName = "overview"
  }
  </code></pre>
