bug#43830: keyboard layout handling incompatible with rest of the OS

[Juri Linkov]

> I use English and Russian keyboard layouts. For every single application I

> Ctrl+S and Ctrl+Ы do the same (S and Ы are on the same physical key). Of

You can use the package https://github.com/a13/reverse-im.el
that was created from code that I wrote to address your previous request
some years ago.
