OK.

That’s a regression.  Localed was added exactly one year ago to fix this
problem in commit 607fcc75404e2b1fc74affcf372b4a6a789ac55e.  I’ve spent
a couple of hours investigating and I don’t know why it doesn’t work,
especially since it works fine once logged in in GNOME (it’s the same
code, GNOME Shell).

OTOH, it has the potential of breaking things here and there; also, I’d
rather stay close to XKB.

If that’s fine with you, I propose applying that patch and adding a
sentence in “Keyboard Layout” to document that.

Damn it, so it’s this ‘terminal_input’ directive that broke it?

That has always been a problem, see
