Another option would be to dynamically remap the 256 text-mode characters as needed, similar to how the mouse cursor is displayed. The average single-language console will have much less than 256 unique characters onscreen at once at any one time, so the average console will rarely have a phyical character remapped once a glyph has been assigned to it. Any more than 256 onscreen at once could be replaced with a special symbol or remapped to a similar character if possible. You could even preferentially replace symbol/line-drawing characters first, and try and preserve characters in the area around the cursor. -- Dan Nelson dnelson_at_allantgroup.comReceived on Wed Jul 15 2009 - 04:46:48 UTC
