Someone with a lot of time could modify syscons to treat the 256 hardware VGA characters as a "window" onto a larger character space, and dynamically remap them as needed. That and a unicode VGA font (like at http://www.inp.nsk.su/~bolkhov/files/fonts/univga/ ) would allow a utf-8 console to display the 256 most common characters on the screen (252 if the mouse is onscreen) whatever they happen to be. -- Dan Nelson dnelson@allantgroup.com
