Converting a LibreOffice-generated PDF form with a ticked checkbox to PostScript leads to an "8" being shown inside the check box rather than the expected "x" sign.
Steps to reproduce:
- Open attached PDF form "simple_form.pdf" in Okular
- tick the checkbox
- print (either to a real printer or use "Print to File (PDF)")
- Look at the output/printout
An "8" is shown inside of the checkbox that has been ticked.
The same checkmark ("x") as displayed in Okular is shown inside the checkbox on the printout.
This can also be reproduced by directly calling 'pdftops' on a PDF form saved after ticking the checkbox:
$ pdftops simple_form_CHECKBOX_TICKED_CLEANED.pdf Syntax Error: Unknown font tag 'ZaDb' Syntax Error: Unknown font tag 'ZaDb'
(In addition to ticking the checkbox, the document has been run through 'mutool clean' to make analysis easier.)
