What a terrible misfeature! Yes, but of course unintentional. Variation selectors work in a similar way. prints two diamonds which is two 1-column wide characters. There has been a recent change in emacs after which it no more prints the variation selectors. This is probably related to the addition of glyphless-char-display-control. Anyway, with Linux it is safest to think the console as an old text-mode VGA display which has been extended to support more codepoitns. > Does term/linux.el get loaded when you run Emacs on that terminal? Yes. GNU/Linux distros are configured to set TERM=3Dlinux at latest in the console getty processes. --=20 Aura
