Try this:

1. Write a curses program (or use the attached one).
2. Call Curses.getch()
3. Press "ä" on your keyboard (Swedish layout needed for this)

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

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

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.
