Description
Created attachment 140724 Sample form generated by LibreOffice
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
Result:
An "8" is shown inside of the checkbox that has been ticked.
Expected result:
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.)
