=============

Like many, you are not understanding unicode because
you do not understand the coding of characters.

You do not understand the coding of the characters
because you do not understand the mathematics behind it.

You focussed on the wrong problem.

(All this stuff has been discussed, tested and worked on
>20 (twenty) years ago.)

Sorry.
