That depends on how you're indexing your PDFs. If you're using acroread,
I'd recommend trying doc2html with pdftotext instead. If you're already
using an external parser or converter, maybe give acroread 3.0 a try instead.


Embedded fonts can be a problem, because there's no guarantee they'll use
standard encodings or even standard glyph names, so there may not be any
way of getting intelligible text out of these documents other than with
your own eyeballs.
