I am using the Verdana font on the PDF, the text on the PDF is not the issue. The issue is the text that is supposed to be retrieved from the form entries.

The Plugin does export the pdf, however the fields that should contain the form entries appear blank.
Please see a sample of the form that gets exported on the link below.
