Use { for a border on left, ` for borders on both sides, } for a border on the right, and _ for a space.

Thanks

I plan to add accented letters... so I might have to put in non-latin blocks...

Some may need a lot of room, if that's the case, I can use sub-squares...

That might take a lot of glyphs to make (and A LOT of pairs) and Fontstruct only supports about 14k glyphs...

Somewhat doable...

Might make opentype alternates for those under Sylistic Set 1...

I made this monospaced so it's easier, If i wanted to, it'd be a lot of work to do that...
