No, we cannot set (with the present API) an arbitrary "binary" string as
the value of the pdf_text_t. That would involve changing the API, which
of course could be done. Internally, the pdf_text_t stores the text
encoded in UTF-32HE (host-endian). If we really need to encrypt/decrypt
whatever data we want, I guess that it shouldn't be stored in a
pdf_text_t. It is in fact something completely independent to the final
purpose of the text module, I think. Anyway, we could extend the text
module for such purpose without any major problem.
