@nikitonsky as a user-defined ligature-ish visual replacement, perhaps.

I thought I like the idea of using unicode until I took part in a project that extensively used words in latvian with the diacritics in db columns and variable names — it didn't feel good at all, the colorators and analyzers broke all over the place and everything felt dirty and unshareable.

Yet then there're apl-like esoterics like uiua.org that manage to make math symbols nice and typable (and some say, even readable).
