If you grab any academic paper (particularly two columns) there is a good chance getting the text out will be hard, and any part of the paper with maths or tables will be unusable. Sorry. I'm away from a computer now, to make a smaller example.

The paper "GADTs Meet Their Match" (first I had in my list) seems to work fine, but I don't know what it was generated with.

  I'll pick on one of my own random papers: https://www.cs.york.ac.uk/aig/projects/implied/docs/cp03.pdf https://www.cs.york.ac.uk/aig/projects/implied/docs/cp03.pdf Try extracting "Theorem 2" on page 5, or any text really. I just get random noise through either a PDF reader, or something like pdf2ascii / ps2ascii. We just made this with standard latex.

    That’s interesting. Did you \usepackage[T1]{fontenc}?

      Thanks paper is from 2003, so I'm not sure. This is just an example. From experience, most PDFs at conferences and journals, generated from pdf, are not accessible to varying degrees.

    Any chance you could post the source code for this? It's using bitmaps for characters instead of proper fonts, which shouldn't happen nowadays. Maybe you should put "\usepackage{lmodern}" at the start? See for example https://tex.stackexchange.com/questions/1291/why-are-bitmap-fonts-used-automatically https://tex.stackexchange.com/questions/1291/why-are-bitmap-... I work with course materials made in Latex, and students sometimes need/want to copy and paste from them, so I try to avoid these kinds of problems.
