One question which pops up regularly in the TeX-groups is "how can I
insert a code listing in my pdf so that it can be copied and pasted

Currently this is not easy as the heuristics of the readers can
easily loose spaces, you can't encode tabs or a specific number of

Real space characters in the pdf (instead of only visible space)
would help here a lot.
