title: Is there anyway to bypass this error on pdfmake? "Type Error: Cannot read property 'syllable' of null"
body: <p>I'm using pdfmake to generate PDF with Sinhala unicode characters using "Iskoola Pota" font. Most of the unicode characters work perfectly. But when the document contains certain characters such as <code>\u0dda</code>, and <code>\u0ddd</code>, it throws this error from fontkit module.</p>
  
  <blockquote>
    <p>"Type Error: Cannot read property 'syllable' of null"</p>
  </blockquote>
  
  <p>(It doesn't throw an error when I use the other common fonts. But I have to use "Iskoola Pota" since I want to display the characters correctly.)</p>
