It should also be pretty difficult because PDFs are binary, not
text...

(They might contain a whole lot of stuff that looks like text, but
there are binary sections mixed into many of them, and I believe
the header at least is binary.  The sample files I'm looking at
definitely are, in any case.  Your solution could not be general.)
