Binary Keyboard Layout -

i've informed myself bit keyboard layouts , tried things dvorak or neo, today asked myself question wether there sort of 'binary' keyboard layout.

it should use 8 keys key in binary representation of 1 character (one byte).

example:

  asdf , jkl; used input. 

if want write 'a' (65 decimal, 10000001 binary) had press a , ;

or wanted write 'f' (146 decimal, 10010010 binary) had press a, f , l.

i wondered if there or show me c/c++ library capable of altering keaboard layout , supporting combinations these.
