John,

Your comments about Mathematica not dealing with "special" characters
makes perfect sense, but my example of

Plot[Cos[x],{x,-Pi,Pi}]

does not contain what I would call "special" characters (these are
simple 7-bit ASCII characters), so what constitutes a "special"
character as far as you or Mathematica is concerned?

I tried the same thing in another program and generated a PDF file
from it. I then tried to copy and paste from Preview and Acrobat Pro
from this generated PDF file into Mathematica and both cases worked
fine. So, Mathematica is definately doing something "behind the
scenes". Anything you could add to help users understand under what
conditions (are there even any?) Mathematica would ever do the "right"
thing when copying and pasting, or can we just assume that Mathematica
generated PDF's will ALWAYS be unable to do a correct copy/paste into
Mathematica?

Thanks...

-Bob
