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.

Does it work in "emacs -Q", without -nw?

(Any reason why you prefer "emacs -nw" to the GUI session?  There's
nothing but disadvantages to that.)

Emacs uses Unicode keyboard input on Windows, so setting
keyboard-coding-system will have no effect, except on Windows 9X.

Then why not mention that in the Elisp manual and perhaps in the doc
string for `set-keyboard-coding-system'?

Eli, good question. Until to 15 minutes ago I thought that only console 
version is accesible by screen reader nvda. But I read a thread on emacs 
list that there is a trick to make it working on gui version too, with 
(setq w32-use-visible-system-caret t).

So I think I'll stop posting bug reports for console emacs, at least on 
Windows.

Thanks
Jarek

Eli, is this something that should be documented (if it's still the
case -- this is a seven year old bug report)?

Right, I amended the relevant documentation, and I'm closing this bug
report.

Thanks.
