That sounds even better than my plan!  If altering the existing bitmap
fonts is on the table, then the CtrlTab style can be dispensed with
entirely, just as I wanted all those posts ago.

One question, though: will expanding the number of glyphs in a single
font beyond 256 cause any internal problems?  Does the redraw engine
assume that the character at a given position can be represented by a
single byte?

Of course, if it doesn't, then that paves the way for... Unicode
StrongED!! :-)
