hi!

i noticed we have the latin subscript small letter n wrong
in the keyboard(6) table. it's set to U+208F, which is an
invalid rune. the first patch corrects that.

i also attached a second patch to have the latin
super/sub-script small letter i available, which i think
could be of use to many of us dealing with math notations.


is it ok to push both? just the former?


best,

-rodri
