Maruan Sahyoun commented on PDFBOX-5686:
----------------------------------------
Please try the sample code below which works for me
{code:java}
PDDocument document = Loader.loadPDF(new
File("/home/msahyoun/Downloads/ZK.pdf"));
PDAcroForm acroform = document.getDocumentCatalog().getAcroForm(null);
PDResources formResources = acroform.getDefaultResources();
PDTrueTypeFont font = (PDTrueTypeFont)
formResources.getFont(COSName.getPDFName("Arial"));
// here is the 'magic' to reuse the font as a new font resource
TrueTypeFont ttFont = font.getTrueTypeFont();
PDFont font2 = PDType0Font.load(document, ttFont, false);
ttFont.close();
// overwrite the preexisiting Arial entry with the new resource
formResources.put(COSName.getPDFName("Arial"), font2);
PDTextField txtField = (PDTextField) acroform.getField("ZP_POJISTENY_OJ");
txtField.setValue("společnost");
document.save("/home/msahyoun/Downloads/ZK-enhanced.pdf");
{code}
The basic idea is that although Arial is being already available in the PDFs
AcroForm resources the fact that it's encoding is set to WinAnsiEncoding limits
to use characters within that altough the embedded font file is also supporting
Czech characters. So what the code does is to read the embedded font file as a
new font and replaces the existing font resource with the new font which is now
using Identity-H (Unicode).
As a result the Czech character can be set.
I'm closing the ticket as this is not a bug but a limitation of the current PDF
form template and a how to question which is better asked on the users mailing
list.. Setting to WinAnsiEncoding and trying to use characters outside of that
will not work and as a result throwing an exception is intended.
So you have to modify the PDF template upfront or on the fly before loading the
XFDF.
