Using 'cat'.  When I start xterm using
    % LANG=en_US.iso88591 xterm
the terminal actually uses ISO-8859-1, but environment variable "LANG" is 
still set to en_US.utf8 for some reason.  Changing LANG to match xterm's 
actual locale makes Emacs behave properly.

So this is basically the same problem as with xterm?  If the display system 
claims it supports iso10646-1, we have to take them at their word?

Oh, well.  I guess I'll make it the choice of character be a customize option 
and let the user deal with it.
