title: Some Arabic Letters are Missing in my PDF
body: <p>I have the following test code</p>
  
  <pre><code>Font arabic = FontFactory.getFont("C:\\Windows\\Fonts\\simpo.ttf",BaseFont.IDENTITY_H,16);
  
       try {
           Document d=new Document();
           PdfWriter writer = PdfWriter.getInstance(d, new FileOutputStream("C:\\Users\\Sana'a\\Downloads\\test.pdf"));
           d.open();
           PdfPTable table = new PdfPTable(1);
           table.setRunDirection(PdfWriter.RUN_DIRECTION_RTL);
           PdfPCell cell= new PdfPCell();
           cell.setBorder(Rectangle.NO_BORDER);
           Paragraph p= new Paragraph(jTextField1.getText(),arabic);
           Paragraph p2= new Paragraph("سناء علاء حسين",arabic);
           p.setAlignment(PdfPCell.ALIGN_LEFT);
           p2.setAlignment(PdfPCell.ALIGN_LEFT);
           cell.addElement(p);
           cell.addElement(p2);
           table.addCell(cell);
           d.add(table);
           d.close();
       }
  
       catch (Exception e) {
           System.out.println(e.getMessage());
       }
  </code></pre>
  
  <p>which prints some text to a PDF file, but the PDF shows some missing letters.
  For example:
  when I write (بيداء عبد الله) in the jtext, the PDF shows </p>
  
  <pre><code>بياء عب الله
  </code></pre>
  
  <p>and (سناء علاء حسين) becomes </p>
  
  <pre><code>سناء علاء حسي
  </code></pre>
  
  <p>any solution please.</p>
