bug#15289: 24.3.50; cannot type non-ascii characters using right alt, cp852, windows console (non-gui cmd terminal)

[Jarek Czekalski]

Before starting emacs with -nw -Q I type unicode x107 character
with AltGr-c. In emacs it does not work, despite doing
set-keyboard-coding-system cp852

It works only in emacs 22.3.1, not in 23, 24 nor in current repo.
I can see the character if I enter it using polish-slash method (/c).
In this old emacs it works out of the box, with pure -nw.

In current emacs AltGr-c is translated into C-g. Similar
simplifications happen to other right alt combination, that
should give me Polish characters.

In GNU Emacs 24.3.50.1 (i686-pc-mingw32)
