It was a function of the EGA/VGA card (maybe CGA? Though I think
that might have been limited to the upper 128 chars while the lower
128 were fixed), not the IBM BIOS.  But yes, there were font-editors
for the EGA/VGA fonts and, once set, they'd appear even in things
like WordPerfect, QuattroPro, Lotus, or Turbo Pascal.  All the rage
back in my 286-wolfenstein3d-playing-turbopascal-programming days. ;-)
