mmmh well, if you consider user-defined character sets in that equatation, 
its getting somewhat messy indeed.... imho you are totally on your own
with that kinda stuff, and the support libraries might not support it.

however, if a macro could be made that takes the location of an upper- and
lowercase character as an input, and which returns the proper value for
vic+0x18 depending on the selected character set the whole thing would be
even consistant for user-defined charsets (which is not bad ofcourse,
just imho not necessary). however dont forget that you will need a second
macro that returns the vic-bank (0xdd00 on a c64) then. also if this
would be done, there should be constants that define the location of the
system charactersets in memory.
