@-symbol not mapped with logical keyboard

[egrath]

Problem:
When using the logical keyboard with a german keyboard layout, the @-symbol is not mapped. Other keys which use Alt-Graph combinations like [,],{,},\ and ~ work like expected.

Desired result:
@-symbol is mapped correctly with german keyboard.

How to reproduce:
Set your keyboard to german layout, run b-em and set the keyboard mapping to logical. Press Alt-Graph+Q to produce the @-symbol. Just a Q is shown.

Sorry it has taken so long to see this. Is this on Linux, Windows or something else?

Hi, it's on Linux and Windows alike.

I think I have an idea what is going in here. First, here is the link to the original implementation of logical keyboard mode: #78

What ZornsLemma ended up implementing is, I think, a hybrid between a logical and physical keyboard mapping, i.e. it assumes that the letter keys are fixed positions and therefore can be handled via the physical translation, while the punctuation and function keys need the logical mapping. As the '@' symbol is on the 'Q" key on the German keyboard this doesn't work. It probably affects other non-English keyboard too.

I will experiment to find a solution.

I was able to reproduce the problem.

See commit https://github.com/stardot/b-em/commits/sf/issue226/ and try setting the keyboard mode to "Logical". The previous mode is renamed hybrid mode.

Oops, the previous link was a branch. The commit is 9dc9ac3.

Steve, thank you so much. Just tried branch sf/issue226 on my main Linux box and it works like a charm with german keyboard layout (Alt-Graph combinations like @, [, ], {, }, , ...).

Will conduct further tests on my Windows machine as soon as I have access to it again.
