"I have read and understood the contribution guidelines.".
Your example in https://github.com/parallax/jsPDF/blob/master/examples/js/basic.js#L390 has a font starts with "AAEAAAASAQAABAAgRFNJRwAAAAEACYzwAAAACEZGVE0YhN+1AAb9lA...", but
when I download it from https://fonts.google.com/specimen/Amiri#standard-styles, it starts with
AAEAAAAPAIAAAwBwR0RFRn5plLoABx9cAAACAEdQT1O...
after converting it on https://rawgit.com/MrRio/jsPDF/master/fontconverter/fontconverter.html . Did you change sth on fonts.google and downloaded it?

I don't know where it was downloaded. Is something wrong with your version?
