@csepp the advantage is that each glyph can be input with a d-pad just as well. It's a pretty clean encode.
I'm working on punctuation mode atm. Let me know if you have any special needs

@neauoire Ooooh, that is pretty smart. I could use that on the DS. 👀
Although for keypad input I was thinking of using a separate "alphabet", since they have different ergonomics and whatnot. But having a single lookup table could save on memory. Hmmmm.
