what version of acrobat reader are you using?  if it's an early one,
you're probably suffering the low-code bug: acrobat refusing to
display characters from code positions 0-31, since the fonts the
designers were thinking of didn't have characters in those positions.

that it makes no difference even if you're using adobe fonts points to
an encoding issue (it wouldn't happen in quite this way if you were
using ly1 fonts).

this is what the -G1 (remapping) switch was invented for, in dvips.
since you're using pdftex, the only solution (afaik) is to upgrade
your acrobat reader to something like 4.05.

beware versions 4.0 and 5, the former had bugs resolved in 4.05, and
there are unresolved confusions with 5 (probably at least some of them
brand new bugs).
