--------------------------------
Summary: National characters not correctly displayed text form
field
Key: PDFBOX-3585
URL: https://issues.apache.org/jira/browse/PDFBOX-3585
Project: PDFBox
Issue Type: Bug
Affects Versions: 2.0.3
Reporter: rumburak
I tried to follow workaround suggested in PDFBOX-3138 to be able to display
czech national characters in PDF form field. I created sample form in
OpenOffice 4.1.3 (file sampleform.pdf) and I created code that adds Type 0 font
to existing PDF font and then it replaces current font used in form field.
I've got 3 problems:
1. After using PDFont font = PDType0Font.load(doc, new
File("fonts/TIMESS__.ttf"));
the font is not loaded into PDF document resources. It is loaded there once it
is used in content stream. OK, I created new dummy page and created dummy text.
Finally I can remove the dummy page and the font is still loaded in PDF
document resources.
2. Czech characters are not displayed, you can see just strange square chars. I
investigated once I use the czech chars somewhere in content stream in my dummy
text then all is displayed correctly (file sampleform_filled.pdf).
Ok, I did the workaround and I have now file sampleform_filled_workaround.pdf
3. Now when in Acrobat Reader I click in field with correctly displayed text I
can see error "Cannot extract the embedded font 'AAAPNQ+TimesSansSerif'. Some
characters may not display or print correctly." This can be workarounded if I
flatten the form using acroForm.flatten(); ( file
sampleform_filled_workaround_flatten.pdf)
I'm not sure about root causes for all 3 issues but the behaviour is strange so
they should be investigated. Attaching java project and PDFs
