strange characters before the font

Asked by Eduard Bürki on 2020-05-25

What do the strange characters before the font mean? Are they from qpdfview or from the font itself? Where do they come from?

Here is what I mean:

Hello Eduard,

I am sorry to be unable to answer your question. AFAIK, these names do come directly from the PDF file and are set by the producer, i.e. I would try to figure the producer out via the document properties and continue from there.

Best regards,
Adam

Thank you for your kindly answer.

When I take the pdf from above an print it with my pdf printer ...

See here:

... and have again a look at the fonts in this printed PDF, then no font names are shown now:

Very strange.

I think this only reinforces that these font names are set by the producing application, i.e. "printing to PDF" means that a virtual printer application will produce a new PDF containing the same graphical elements while it is by no means bound to reproduce the original font embedding structure.

Can you help with this problem?
