What kind of fonts am I able to use when creating a PDF report? It seems that I can't use any font.
You need to set the PDF generation to not use only the internal fonts. You can do this in the WindwardReports.properties file by setting:
pdf.font_level=1 # or 2
or in your code with the call:
ProcessPdf.setFontLevel( ProcessPdf.FONT_NO_EMBED); // or FONT_EMBEDDED
