I'm trying to fill out a AcroForm's textfield with iTextSharp. The Acroform textfield was created also by iTextSharp by this piece of code:
TextField Field = new TextField(OutputWriter, FieldPos, "MyField");
OutputWriter.AddAnnotation(Field.GetTextField()); // OutputWriter is writing to form.pdf
I fill the form using this code:
PdfReader reader = new PdfReader("form.pdf");
PdfStamper filledOutForm = new PdfStamper(reader, new FileStream("filled_form.pdf", FileMode.Create));
AcroFields form = filledOutForm.AcroFields;
form.SetField("MyField", "some unicode data");
However, when I open filled_form.pdf in Acrobat Reader, unicode characters are not visible unless I edit manually the field (e.g. I append a character by hand to the field).
I also tried to set field's font by:
BaseFont fieldFontRoman = BaseFont.CreateFont(@"C:\Windows\Fonts\times.ttf",
BaseFont.IDENTITY_H,
BaseFont.EMBEDDED);
form.SetFieldProperty("MyField", "textfont", fieldFontRoman, null);
Then, when I open filled_form.pdf in Acrobat Reader, everything looks fine unless I edit manually the field. After that, non unicode characters disappear (they change into blank spaces). They are here in the field because if I copy whole content of the field by CTRL + C and paste it to notepad, I can see all characters.
Please advise. I would like to see all characters in the field without the need of editing the field manually and of course after editing it manually I would like no characters to disappear.
Thank you
