3) What I expect to happen:
In KDE, when I press the tilde key (AltGr + key immediately left to backspace), a tilde (~) should appear

4) What happens instead:
A caret (^) appears. This is the symbol that is mapped to that key without AltGr.

N.B. It does work if Swiss German is chosen, rather than Swiss French. However, normally the only difference between these two variants is supposed to be the characters öäü which switch position with
éàè, and nothing else. Moreover, even in Swiss French, all other AltGr combos do work, so it's not as if simply the AltGr modifier was being ignored.

(N.B. I suppose the relevant package is indeed plasma-workspace, as this is the package that owns the file /usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/plasma/workspace/keyboardlayout/libkeyboardlayoutplugin.so . If this is not the right package for this bug, please feel free to re-categorize it)

Actually, I was mistaken on this. It does work ok for whatever layout is
the default (i.e. topmost in list shown in
System->Settings->InputDevices->Keyboard->Layouts->ConfigureLayouts)

I.e. If I move Swiss French to the top, and Swiss German second, then
tilde works ok in Swiss French, but no longer in Swiss German.

All other AltGr combos, include dead-acute work ok in both variants.

Thanks,

Alain
