The keymap `de-e1` does not map the F key of a German keyboard to lowercase f.

I am assuming here that the keymap with identifier `de-e1` corresponds to the
[E1 German keyboard layout][1], so hitting the F key should produce f. I tried
a few other keys and they work as expected, for example AltGr+^ for
multiplication cross (���).

To reproduce, use a Tumbleweed minimal VM and set the keymap with
```
localectl set-keymap de-e1
```
Then type `ASDFG asdfg` into the prompt.

The virtual console should show `ASDFG asdfg`, but instead it shows `ASDFG
asdg`.
