Yes, a few more are possible. But it does not work to set Terminal into 
Latin-9 mode, set LANG to *.UTF-8, and think GNU Emacs could now output 
UTF-8. This will fail.

Use these envvars (the version number could be different):

TERM_PROGRAM=Apple_Terminal
TERM_PROGRAM_VERSION=100.1.4

Yes, that's right.

In Terminal. As a stand-alone application I can't see it. But I'll 
investigate my failures ...

The fontsets that work fine in X11 don't work in Carbon, even when I 
change the encoding to those Carbon Emacs sees when I invoke 'M-x 
set-frame-font RET TAB TAB.' Here too some investigation is needed.

Then it could be unchaged? The default could be Mac-Roman ... The 
setting is in Terminal -> Window Settings -> Monitor (item #5 from the 
chooser).
