Subject: process_unicode: Small refactor & linux fix

This moves the unicode input start / end sequences into their own
functions, so keymaps and other functionality can build on it too.

At the same time, it changes how the Linux variant works, to match
reality: CTRL+SHIFT must be unregistered too, and we close the thing
with a Space instead.
