title: Standard token for encoding parentheses for HTML Ids?
body: <p>I have to encode strings to remove parentheses for Ids for HTML elements.</p>
  
  <p>Parentheses (these ones <code>(</code>,<code>)</code>) aren't valid in HTML Ids, are there standard strings (like <a href="http://en.wikipedia.org/wiki/Percent-encoding" rel="nofollow">those used in URLs</a>) to use?</p>
  
  <p>Is there an existing method that can be used in ASP.NET MVC?</p>
  
  <p>N.B.  <code>System.Web.Mvc.HttpUtility.HtmlEncode(string)</code>, does not encode parentheses.</p>
