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

Author: walles (Johan Walles)
Status: Open
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 "辰" on your keyboard (Swedish layout needed for this)

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

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

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.
