Both WhoisAction and WhoisHttpAction set the HTTP response content type to "text/plain". There is no need to defensively escape the content. In fact, by escaping the content, it creates more problems down the line.
When used in a website, the response should be written into a DOM node by setting the textContent of the node, which automatically escapes the content.
