Cannot display HTML string

I am struggling with display string HTML in Android WebView.

On the server side, I downloaded a web page and escape HTML characters and quotes (I used Python):

my_string = html.escape(my_string, True)

On the Android client side: strings are unescaped by:

myString = StringEscapeUtils.unescapeHtml4(myString)
webview.loadData( myString, "text/html", "encoding");

However webview just display them as literal strings. Here are the result:

Edit: I add original string returned from server side:
