The simpler solution (workaround?) is to use loadDataWithBaseURL(String, String, String, String, String). Calls to this method do not require escaping. Pass along a garbage base url (or null), and an empty or null history url for success and profit.
webView.loadDataWithBaseURL("blarg://ignored", getData(), "text/html", "utf-8", "");
