bug#5235: 23.1; Unibyte keyboard input problem

[Tomasz Zbrożek]

Hi,
In Emacs 23.1, in unibyte mode (emacs --unibyte) and with windows-1250
coding I can't write Polish chars with right Alt key.  For example right Alt 
+ 'a' gives ^E on the screen. In Emacs 22.3 it works fine (I see polish 
char 'ą'), but there there is other problem that buffer is printed in 
iso-8859 even if I configure Language Environment to use windows-1250.  In 
23.1 with such Language Environment (configured to use cp1250) polish special 
chars read from file are printed correctly (I see them) but I can't write 
them using right Alt key (or even input mode polish-slash).

I checked it on GNU/Linux and also on MS Windows XP (pure NT-Emacs and 
EmacsW32), it's the same problem.

Regards
Tomek
