Bug #975: ruby curses extension does not support multibyte characters

• Status: Closed
• Assignee: -
• Target version: 1.9.1 RC2

[hramrach (Michal Suchanek)]

=begin
ncurses supplies a ncursesw library that works as drop-in replacement for the ncurses with added multibyte character support. Just updating the library test enables printing UTF-8 for me.

test (run with ruby -KU) in utf-8 locale:

require 'curses'

test_string = "あ"

Curses.init_screen

Curses.addstr test_string

Curses.refresh

Curses.getch

Curses.close_screen

STDOUT.puts test_string
=end

As far as I know, ncursesw is NOT a drop-in replacement. It has whole
new API around cchar_t, wchar_t and wint_t, e.g. wadd_wch in place of
waddch. Am I missing something?

Yes.

You do not need to use that additional wide character API to get utf-8
characters printed on the screen.

Thanks
