Azerty layout could certainly map shift-space to unbreakable space too

But honestly, rather than changing keyboards (which is hard), why doesn't Google just pick a shorthand that doesn't break typography rules, like `@` instead of `:`

If triggering it by accident wasn't intended, they could have used a regular keyboard shortcut like Alt+Shift+E or even instruct users to press Win+. to use the system-wide emoji menu.
