Maruan Sahyoun commented on PDFBOX-3924:
----------------------------------------
what is the error you are getting? If it's because of
{code}
U+xxxx is not available in this font's encoding: WinAnsiEncoding
{code}
that doesn't have anything to do with flatten but with trying to set a fields
value where the characters you are using are not part of the encoding set for
the font. Could you be a little more specific what the issue is you are facing?

> PDAcroForm acroForm = pdfDocument.getDocumentCatalog().getAcroForm();
> acroForm.setNeedAppearances(true); //need this line for Hindi
