Debian has an easy line in /etc/default/console-setup.  The default is
now utf8 but there's lots more.  I have it latin1.

I think I'd like char-displayable-p to obey terminal-coding-system too
like those parts, since that is the bytes which are sent out.

I imagine making minimal enquiries into the console settings would be
both less thinking needed in emacs and more give the user what setup
they chose.  Doing stuff to change the mode doesn't sound good.
