title: Certain HTML entities (arrows) are not rendered in PDF (iText)
body: <p>I tried to render <code>&amp;rArr; &amp;hArr; &amp;euro; &amp;copy; &amp;rarr;</code> in the HTML with the XMLWorker and iText. Only the copyright and euro symbol appear in the PDF. I used the dafault font and Arial but without success.</p>
  
  <p>Is there a way to get those entities rendered? Is there an alterantive way to render arrows in text?</p>
