By partially, I meant that only a single character of a single key
wouldn't load. I'm curious, what would be the implications here ? How
could it break ?
I tried loading this keymap, and didn't see any averse effect. The
character was missing, and that's about it. Why wouldn't we want that ?

I thought about doing this too, but it would mean not recognizing a
valid (albeit unsupported) unicode symbol. At least here the parsing
works, even if this particular symbol isn't loaded because of kernel
It feels weird to use the U+ unicode symbol notation, and then refuse to
load 2/3rd of those.
