If ansi wants this to really work, they'll have to allow for
16 bit char's, the standard in Japanese and Chinese language
word processors.  There is still a problem with
using the 8th bit, as many machines generate strict parity
for character work.  Assumably, the lexical ordering probelem
can be eliminated by stripping the 8th bit before comparison,
or better yet, 15 bit char's with 1 bit parity, or any
other combo.
