title: How to not encode RestSharp parameter
body: <p>I need to pass one of parameters to HttpRequest (POST).</p>
  
  <p>Lets say we have '<strong>someParam</strong>' parameter and we need to pass '<strong>some+value</strong>' value.</p>
  
  <p>When using <strong>request.AddParameter("someParam", "some+value");</strong> - value is automatically converted to '<strong>some%2Bvalue</strong>' and in request it looks like '<strong>someparam=some%2Bvalue</strong>'. But the application only understands <strong>+</strong>.</p>
  
  <p><strong>Is there any way how to add parameter to request but don't encode it???</strong></p>
