Does not seem like a good idea. Of course it's Turing complete. Heh

PDF is a text format with the possibility of having various stream
filters inside it. 

The following text is a valid PDF file from the PDF specification:

As per my admittedly limited understanding BER is a format for
establishing Binary Encoding Rules, and not a binary format itself. In
other words I have always understood it to be text, a quick google seems
to confirm me in this belief, if you can show me elsewhere that this is
not so I would be appreciative.
