Hi Maruan,
> you can change your code like this to use Helvetica.

you saved my day, sir! It works like a charm, thank you very much.
To summarize it - I encountered two problems:
1. "Invisible" form field content.
Workaround: Setting 'pdAcroForm.setNeedAppearances( false )', filling
the fields and setting the property to 'true' again.
2. Wrong encoding / weird special chars in form fields.
Workaround: Using a PDF default font. In my case, setting the font of
all form fields to 'PDType1Font.HELVETICA' worked.
Can I contribute something to these problems, maybe creating a JIRA issue
(for the first item), or is PDFBOX-3332 sufficient for the moment?
Thanks again (also to you, John) for all your support
Best Regards,
Timo

you can change your code like this to use Helvetica.
pdAcroForm.setNeedAppearances(false);
// Setting PDF field content in "textfield01"
PDField pdField = pdAcroForm.getField( "textfield01" );
PDType1Font helv = PDType1Font.HELVETICA;
// add the font to the AcroForm Resources
pdAcroForm.getDefaultResources().put(COSName.getPDFName("Helv"),
helv);
// Set the default appearance to use that font.
// Note: this was harcoded from the original value of
// 0 0 0 rg /F2 12 Tf
// which is not totally correct as the font should be the first
parameter
((PDTextField)pdField).setDefaultAppearance("/Helv 12 Tf");
pdField.setValue( "test content" );
pdAcroForm.setNeedAppearances(true);
