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
