Mavericks has wrong Russian layout Looks like the Russian layout included in Mavericks has wrong characters mapping. The layout image in preferences looks correct (see the image). But actual mapping of punctuation characters resembles the DOS ones a decade ago. E.g., to enter comma or dot i need to press Shift-6 and Shift-7 respectively, instead of Shift-? and ?.
This was a forced upgrade from previous mac os x version by my company. Any ideas how to install correct Russian layout?
My Russian PC layout works correctly.  It sounds like you are using Russian instead.  Make sure you have the Russian flag with the PC underneath showing at the top right of the screen.  Or that you have the layout called Russian removed from your active Input Sources.

If you have the right flag showing, do you have this problem for all apps including TextEdit?
