I have seen this sort of problem a few years ago with AR 3.x and
early versions of pdftex -- since TeX encode the math minus as
ASCII NUL it often breaks early versions of software that attempt
to use "standard" C null-terminated strings.  Glyphs encoded as
ASCII control characters have also caused problems, which is why
some systems reencode those glyphs, but I haven't seen the problem

What version of pdftex?  I have (on assorted unix systems and Win95):

Version 3.14159-1.00a-pretest-20010806-2.1 (Web2C

What version of Acrobat Reader are you using?  4.05 works well, I'm
not sure of the status of the 5.x versions.  What happens when you
display the file using the current gsview (which will nag you to
purchase a license, but can be used without an up-front payment).

If all this doesn't help, please put a small example with the TeX
source and the pdf on a public server somewhere (preferably without
pdf compression) so we can analyze the problem.
