Re: I've made a simple program, showing UTF-8 lower but not uppercase working

[amores perros]

Myself asking another probably very simple question.

I installed libncursesw5-dev, and changed my test program
by including ncursesw
#include <ncursesw/curses.h>

and linking to ncursesw
gcc ct.c -lncursesw

and it worked this time (that is, both lowercase and uppercase
characters in my simple test program came out correctly).

I did not add code to convert my string to wchar_t,
and change my calls to call widechar (cchar) versions.

I did not define _XOPEN_CURSES.

Did I get lucky (and I should go back and define _XOPEN_CURSES,
and ignore this flaky result), or should this have worked?

Cordially,

Perry
