(Note that this is some form of data corruption.)

If I run ps2pdf on the PDF file from

  https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3163.pdf

the text

  arithmetic. Also, C99’s informative annex G offered [...]

is changed to

  arithmetic. !lso, C99’s informative annex G offered [...]

i.e. the letter "A" is changed to the exclamation point "!".

Note that this is a regression: there is no such issue with the
ghostscript 10.0.0~dfsg-11+deb12u1 package under Debian 12 (bookworm).

The above PDF file was generated with Microsoft Word, and an
uncompressed stream shows unusual content. This is where the
bug occurs.

I've reported the bug upstream and put more technical details
there.

Fixed upstream, and I could check that this is also fixed
in 10.02.1~dfsg-1.
