I'm a bit of a typography buff, so just chiming in to say that there is nothing inherently wrong with ligatures in PDF! As far as I understand, PDFs can be generated such that ligatures can be correctly cut'n'pasted from most PDF readers. I have seen PDFs where ligatures in links (ending in ”.fi”) cause problems, and I believe that's just an incorrectly generated PDF; ligatures done wrong. Considering that PDF a programming language designed to draw stuff on paper, going backwards from the program back to clean data is not something that one should expect to always work.
