title: iText XMLWorkerHelper font with CE characters
body: <p>I have troubles with converting HTML to PDF with iText XMLWorkerHelper. Document is genereted fine but it end up without some central European characters (Croatian letters like č, ć, đ, ž).</p>
  
  <p>When I write text without XMLWorkerHelper and define font same text from databese is written correctly:</p>
  
  <pre><code>Dim fntArial As BaseFont = BaseFont.CreateFont("Helvetica", BaseFont.CP1250, BaseFont.NOT_EMBEDDED)
  Dim fontText10 As Font = New Font(fntArial, 10)
  </code></pre>
  
  <p>But when I use XMLWorkerHelper CE characters are lost.</p>
  
  <pre><code>Dim pdfDokument As New Document()
  Dim docContent As String = "&lt;style&gt;" &amp; _
                             "@font-face {font-family: 'Arial'; src: url('fonts/arial.ttf') format('truetype');}" &amp; _
                             "body, td, div, span{font-family: 'Arial'; color: #253f60; font-size: 12px;}" &amp; _
                             ...
                            "&lt;/style&gt;" &amp; _
                            "HTML content from database"
  Dim wrtPDF As PdfWriter = PdfWriter.GetInstance(pdfDokument, New FileStream(Request.PhysicalApplicationPath &amp; docName, FileMode.Create))
  pdfDokument.Open()
  Dim worker As XMLWorkerHelper = XMLWorkerHelper.GetInstance
  worker.ParseXHtml(wrtPDF, pdfDokument, New StringReader(docContent))
  </code></pre>
  
  <p>How can I embed CE font to PDF document and set is as default font for XMLWorkerHelper?</p>
