We can have input methods switched on and off depending on surrounding
characters, but how will this solve the problem that different methods
of inputting the same character behave differently with mirrored
characters?  A user can conceptually type a character either via an
Emacs input method or via the OS keyboard, in the same place, can't
she?

Are you saying that Emacs should have a way of knowing which OS-level
keyboard layout (or keyboard language, in Windows parlance) was used
to insert the character?  If so, how to do that?

Or are you saying that switching on a suitable input method, depending
on surrounding characters, will eliminate the need to know how the
character was inserted?  If so, please explain why you think so,
because I don't follow.

I don't need to record that, I just need to know that when the
character is inserted.  After it's inserted, this information is not
needed anymore, because display-time mirroring has enough information
to DTRT.
