Bug #9094: Curses.getch() function responds twice for unicode keys
https://bugs.ruby-lang.org/issues/9094#change-45051

* Author: Johan Walles
* Status: Third Party's Issue
* Priority: Normal
* Assignee: 
* Category: 
* Target version: 
* ruby -v: ruby 2.1.0dev (2013-10-30 trunk 43476) [x86_64-darwin13.0.0]
* Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN
----------------------------------------
Try this:
1. Write a curses program (or use the attached one).
2. Call Curses.getch()
3. Press "��" on your keyboard (Swedish layout needed for this)

Current result:
I get *two* separate results from Curses.getch(), which when merged form a unicode '��'; 195 and 164.

Expected result:
I expected *one* result from Curses.getch() for my single keypress, containing a unicode '��'.

Notes:
It seems as if Curses.getch() ends up in the NCurses getch() function at http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/trunk/ext/curses/curses.c?revision=43316&view=markup#l647 . Calling wgetch() instead may or may not help.
