Sticky keys in plain tty mode

[unxed]

In plain tty mode (--nodetect) sticky keys with control are working a bit strange.

If you press Ctrl+Space and then L, nothing happens. But if you hold Ctrl+Space and press L, information panel appears.

Ctrl+Space+numbers are not working at all.

Bug does not reproduce on Arch / X11 / KDE.
Tested in Virtual Console, Konsole, GNOME terminal and kitty.

UPD: but the second attempt, made a little later, was successful. the same behavior. strange.

UPD2: well, found the reason for this behavior on my side:
Ctrl+Space, L does not work when the Russian keyboard layout is selected.
Ctrl+Space+L does work, though.

Ctrl+Space, and numbers work in all cases.

Non-Latin keyboard layout is required to reproduce, confirming.

Bug with digits reproduces for me on 2.6.0 from Ubuntu 24.04, not reproduces on master.

Ctrl+Space, L starts Macro recording.

@unxed can you check it on your side?

Yep, something strange is here.

Same on Mint, Cinnamon, X11.

Don't yet understand how to solve this, because in the console I don't see a way to determine which Latin key corresponds to the received Russian character. In wx we have a raw key code for this, but in console we don't.

As expected, the bug is not reproduced in Xi and kitty modes.
