+i use [XCompose][] to input quox code with the nice unicode characters. here's the relevant parts of my compose map, so you can use them without having to write them all out for yourself.

+- "⎄" is the button you mapped the compose key to.
+- 𝑖, 𝑗, 𝑘, 𝑙 don't actually mean anything special, i just like to use them for dimension variables.
+- the bindings for →, ⇒, and × _probably_ already exist in the default map.
+- 🐉 isn't used in the language itself but it's the main branch name :3
