LOL @ jonathan01 – You’d certainly think so wouldn’t you. I’ve had the misfortune of encountering PDFs with all rasterized text. Which if you don’t already know generally means that all the text has been converted to graphic form. This essentially renders it unsearchable typically. You just can’t take anything for granted these days.
Well that’s because whoever created it doesn’t understand the PDF format as you say – if you create in a format that exports to a proper PDF that is using text then no problems – of course ours are done the correct way.
