title: What is the name of the function, which does the opposite to HttpUtility.JavaScriptStringEncode?
body: <p>I need to evaluate escape sequences on the string.
  To escape the string, HttpUtility.JavaScriptStringEncode or something similar was used.
  How do I do the opposite transformation?</p>
  
  <p>Here's an example:</p>
  
  <pre><code>        var s = @"otehu""oeuhnoa
          oaehu
          oatehu
          oeu";
          var t = HttpUtility.JavaScriptStringEncode(s);
          var n = Decode(t);
  </code></pre>
  
  <p>i need such function Decode, which would make n == s;</p>
