> I have no idea how to type emojis on Linux (with a barebones tiling WM)
You can copy and paste. In the context of this project, the small, fixed set of symbols (not emojis, but whatever) makes a lot of sense, and the code comes with an example that you can copy from. I would guess that this works even on Solaris or in a decent editor on GUI-less FreeBSD.
As for using, I don't know, "thumbs up" and "thumbs down" symbols in place of "true" or "false", sure, that would be excessive.
The FreeBSD base system ships with two editors (IIRC): ed and nvi. Ed doesn’t let you copy and paste at all, except whole lines. I don’t know for sure, but I’d guess that nvi does work properly with Unicode. But can the base system’s font render it properly? I don’t know.
Anyway, that’s beside the point. It’s an unnecessary piece of additional complexity for, as far as I can tell, no real benefit over escape sequences.
