Please explain what characters are on this key (normal, shifted, alt-gr, shift alt-gr).

Depends on the map. sys/dev/pckbc/wskbdmap_mfii.c is built around XT scancodes.

This is a compose table to be used if your keyboard is missing some characters.
If your keyboard has for example Aumlaut, you don't need <Compose A ">.

While the input is a more or less abstract scancode (Just numbers) the MI output
is already close to 16-bit unicode.

Doesn't work, because no keyboard has enough spare keys for all these characters.

If shift-4 is not $, either your keyboard or the map file are wrong.
