It doesn't. With switching Emacs input methods between English and Russian
I also get English '/' == Russian '.'. And so C-. in Russian input method
works
as C-/ in English, because it's the same physical key.

Yeah, one of those is mine. It doesn't work "fine", it works much better
than
nothing. But still not exactly fine. I rebound C-. as a workaround, because
anyway it has no standard binding. But I cannot do the same for M-. for
example.

Also, the same goes for many S-M-[digit] combinations, because characters
on the digit row are often different in Russian layout. For example, S-M-6
in
English layout translates to M-^, `delete-indentation', but in Russian S-M-6
becomes M-:, `eval-expression'. And so on.

So, it is a good workaround that *mostly* works. But it doesn't solve the
underlying issue. Which was successfully solved by other applications tens
of years ago.
