Full Unicode patch with RTL Support & BiDi logic.

This commit is well documented, so no need to tell you my life story.

Full Unicode patch with RTL Support & BiDi logic.

Removed the legacy codePage, normalised to UTF8 (65001).

It also comes with:

CTRL + A : select text (highlighted)
CTRL + C : copy
CTRL + V : paste
CTRL + X : cut
CTRL + Y : redo
CTRL + Z : undo
