Dear Emacs gurus
Run the script below to see an interesting failure. These 3
ingredients are needed:
1. The environment variable LC_CTYPE (or probably LANG or LC_ALL, but
I haven't checked those variables) must be set (probably to a UTF-8
locale, but I haven't checked any locales other than "C" (no bug)
and "en_US.UTF-8" (bug)).
2. The --no-window-system command-line argument must be used.
3. The variable utf-8-compose-scripts must be set.
At this point, various things start failing strangely. The script
demonstrates one of the failures.
I hope this helps.
Joe

# You will now see an error message like this one (replace XYZZY by
