Possible defect: Does not display unicode after "Flattening"

[Aftab Mahmood]

When I fill in a pdf form using itext and then flatten it by "stamp.setFormFlattening(true)" . then resulting pdf does not show Unicode text in any pdf reader. Is it known limitation?

Which iText class should I use to read contents of a page from the pdf file?

Please provide a sample PDF before and after flattening the demonstrates this, since it is unclear exactly what you mean…

Maybe you aren't providing the fonts that allow flattening.
I can't tell for sure, I don't know what you're doing.
Nor do I know what you get as result.

I have attached before "test_utf_3.pdf" and after "generatedPdf.pdf" files.  I have also attached the code that I am using to fill in forms.

 I have verified that 

#1- at the time the value is set in the code, the debugger shows correct value unicode value for the AcroField.

#2 - if I don not "flatten" the fields then "generatedPdf.pdf" show unicode text correctly. 

So I don't think it is font issue until unless there is a special requirement for an additional font setup before "Flattening" . Is it?

You must add a substitution font in AcroFields.

I dont understand this requirement . User provides me a pre-designed PDF that supports Unicode. My service fill in some information and returns it to the user.  How can I know which font to substitute with.

Second I tried to substituted font (with different encodings) and was not able to get the results. Here is my code:

BaseFont bf= BaseFont.createFont("c:/windows/fonts/COUR.ttf", "utf-8", BaseFont.EMBEDDED);    

        formFields.addSubstitutionFont(bf);

Any suggestion?

The suggestion is to read the documentation preferably the book. "utf-8" is
not a valid encoding in PDF, use Identity-H. There's nothing magic about
needing a substitution font, that's what Acrobat does behind the scenes. All
this was discussed several times before in the mailing list.

Thank you Paulo....  It did work ... by hard coding many font  with "Identity-H" encoding .. I do have the book... and has read chapter 16... since there was no reference to substitution font.. so was not able to connect the dots...with chapter 8.  

I need one more favor if you provide me some pointers... Instead of hard coding  fonts i want to read fonts information from the document its self. I tried using "BaseFont.getDocumentFonts(pdfReader);" but it always return null.  Is there any other API that I can use.
