Consider "C-s" `isearch-forward' followed by "M-s i" 
`isearch-toggle-invisible': "C-ы M-ы ш" with bare "ш" should work as 
"C-s M-s i" but "ш" bound to `self-insert-command' should insert "ш".

Taking into account which way some applications are localized, perhaps 
there are users who rarely switched to a Latin (e.g. US) keyboard 
layout. E.g. spreadsheets may have translated function names, not to 
mention accelerator keys.

There should be a way to specify whether symbol is from the base (Latin) 
keyboard layout or from localized one. E.g. "," and some other 
punctuation characters are jumping. Perhaps it may be achieved by 
additional virtual modifier: "L-," should be matched against localized 
layout. However user may have multiple non-Latin layouts configured and 
GNOME reconfigures XKB on each layout switch to 2 groups: Latin and 
current one.
