Sure! The PDF I'm having trouble with is this one:
http://ia700100.us.archive.org/21/items/gov.uscourts.nysd.321800/gov.uscourts.nysd.321800.28.0.pdf
For example, if you look at page 10, the phrase "transfers designed to obscure the illicit origin of the USD" is a regular ASCII string. The phrase ' - thereby "cleaning" the money - before' is a hexstring, probably because of the smart quotes. And then the phrase "transferring it to clients seeking to purchase USD" is a normal ASCII string again.
I tried the same code on a few other PDFs and didn't see any similar problems, so it's possible that this specific PDF is screwed up.
Thanks again for your help.
