Do I interpret the PDF specs correctly that if encryption is applied it
doesn't make sense to apply ASCII85 or ASCIIHEX filters, because the
generated PDF will always be binary and the filters only increase the
file size? So, these two filters could be disabled in this case. Right?

Here's the key paragraph from PDF 1.3, page 64:
> Stream data is encrypted after all stream encoding filters have been applied (and is
> decrypted before the stream decoding filters are applied). Decryption of strings,
> other than those in the Encryption dictionary, is done after escape-sequence
> processing and hex decoding as appropriate to the string representation described
> in Section 4.4, “Strings and text.”
