This issue is due to text annotations and needing to package the font inside the PDF so that it renders correctly. I can add an option in a future update to not package fonts in the PDF, which will result in the text annotation being converted to use whatever font the PDF viewer defaults to. This can drastically change the appearance of the font though. I can also consider adding an option to convert text annotations to images, but this may also increase the PDF file size, as images use a lot of space.
