Subject: Re: curses - how to use unicode

[snip]

I have compiled ncurses-5.4  with --enable-widec --with-shared.
I now have a "libncursesw.so" file.. 

I am still unsure what function I should use in order to output UTF-8
encoded strings.. or if I should output with another unicode encoding?


require 'dl/import'
module Curses
	extend DL::Importable
	dlload "libncursesw.so"
	typealias "WINDOW", "void*"
	typealias "wchar_t", "unsigned long"
	extern "int add_wch(const char *)"
	extern "int addstr(const char *)"
	extern "int cbreak()"
	extern "int curs_set(int)"
	extern "int endwin()"
	extern "int getch()"
	extern "WINDOW initscr()"
	extern "int noecho()"
	extern "int refresh()"
	
	# is const char * correct here ?
	extern "int add_wchstr(const char *)"
	extern "int add_wchnstr(const char *, int)"
end

str = [0x250c, 0x2510, 10, 0x2514, 0x2518].pack("U*") + "\000"
p str  #  -> "\342\224\214\342\224\220\n\342\224\224\342\224\230\000"
puts str   # this renders a nice box
gets

Curses.initscr
Curses.cbreak
Curses.noecho
Curses.add_wchstr(str)  # no box.. 
Curses.getch
Curses.endwin
