ok, this is what Denemo receives on my Debian installation, so whatever
is going on should be fixable, though it is likely to involve some Gtk
murk - Gtk supplies names for key presses, IIRC, in two ways depending
on whether they should be translated to the user's language or not.

Let's concentrate on the simplest case - pressing "b" on your keyboard:

To be clear, when you try to set the (unshifted, no caps locked, no
alt, no ctrl) key "b" as a shortcut you find that Denemo describes it
as keypress "2"?

As a first step it would be good to uncomment the lines

src/core/kbd-custom.c: 415, 444, 445, 482
in the file src/core/kbd-custom.c

these are print statements that will step through the munging, I think,
and tell us what Gtk is calling the keypress.
