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!) .
