Javascript Encode on server side - Medium Trust Environment

  return Microsoft.Security.Application.AntiXss.JavaScriptEncode(text, false);

Unfortunately, It doesn't work in Medium trust environment - btw, why the hell i get stingy clients. After some time digging all over internet and trying to write it by myself I accidentally found a thing that I never believed to be there.

public static string JavaSriptEncode(this string text) {
  return HttpUtility.JavaScriptStringEncode(text);
