I have a PDF document which, for some reason, I can't copy and paste or search in. The PDF is a text-based and not image file. When I try to copy and paste the text into Microsoft Word or GNU Emacs, I get a lot of small boxes in place of the letters. When I try to search the text in Adobe Reader, I can't find words which I can see are there. The document doesn't seem to have any special protections applied to it. I've had PDFs once or twice before. I tried opening it in Google Docs but again, although it comes out as clear text, I cannot search it. Does this ring any bells with anyone?
I tried looking at the fonts of the PDF and it looks like this:
--font-65795-6-- (Embedded Subset) Type: TrueType Encoding: Built-in Century (Embedded Subset) Type: TrueType Encoding: Built-in
followed by similar lines for Century, Helvetica, Symbol, Times-Roman, and Verdana.
