unicode saving space(s!)

11.16: adde/unicode/saving space(s!):
. in addition to the idea where
some codes are mapped to words,
a range of chars can be for word parts:
a case stmt can check for code range to chg mode:
if case not in math
and other english symbols:
if case less than ascii limit
it is word mode,
else if case less than word mode limit:
it is word`parts mode .
. the key idea of word parts mode
is the classification into {prefix root midfix suffix} .
. if there's a distinction between midfix and suffix
then can have word`part strings that are
separated not by spaces
but by part-classes -- saving a lot of space(s!) .
