Hi Tilman, so tried to follow your advice and installed the Zapf Dingabts font. Unfortunately, the conversion result is still empty. I also downloaded the PDFDebugger and had a look myself inside the PDF structure. As far as I understand, there are 3 fonts used in this document: Arial, TimesNewRoman & Arial0. So there seems to be no Zapf Dingbats font... Anyway - I debugged again inside the conversion. The exception occurs for the Arial0 font. So here is a codde snipped where we iterate over all fonts used in this document:
for (COSName name : document.getPage(page).getResources().getFontNames()) { PDFont font = document.getPage(page).getResources().getFont(name); ... } for name=Arial0 there will be the exception. Also the font table of Arial0 looks a bit different than the other ones. I also tried to install this specific font, but it seems that there does not exist such a font 'Arial0'. Besides that, Arial sounds very basic to me and should be available on every windows system i guess. There is some more question arised during this investigation: How does it work for other viewers like the Adobe Acrobat viewer, or inside chrome/firefox and of course the PDFDebugger? For these viewers, there are no problems at all. Is it not required for these viewers to have the corresponding fonts installed as well? All in all, i am a bit confused & i don't know how to proceed from this point. Many thanks in advance & I am looking forward to hear from you.
