Has anyone else the same problem, and eventually more info about it? Or even a solution/workaround?
could you please attach one of your PDF files along with a screenshot of the way it's rendered by Firefox's built-in viewer?
I'm experiencing the same issue using Firefox and Chrome built-in viewers using embedded fonts.
You'll find here in attachment a sample PDF generated by your library and the simple snippet of code I used to generate it.
I woulk like to ask to the author of this thread if this is the same issue he's experienced and if he managed to find a solution.
