Reading ncurses stdin in UTF-8

Question

In my Linux program being developed in C with ncurses, I need to read stdin in UTF-8 encoding. However, when I do this:

wint_t unicode_char=0;
get_wch(&unicode_char);

I get a wide character encoded in utf-16 (I see this when I unload a variable using gdb). I don't want to convert it from utf-16 to utf-8, I want the input to be in UTF-8 all the time, no matter which Linux distribution runs my program with any other language that the user has configured. How it's done? Is it possible?

EDIT : Here is an example of a source and evidence that get_wch uses UTF-16 (which is the same as UTF-32) and not UTF-8, despite the fact that I configured the input source of UTF-8 using setlocale ().

[niko@dev1 ncurses]$ gcc -g -o getch -std=c99 $(ncursesw5-config --cflags --libs) getch.c 
[niko@dev1 ncurses]$ cat getch.c 
#define _GNU_SOURCE
#include <locale.h>
#include <ncursesw/ncurses.h>
#include <stdlib.h>
#include <stdio.h>
#include <string.h>

int ct;
wint_t unichar;

int main(int argc, char *argv[])
{
    setlocale(LC_ALL, ""); /* make sure UTF8 */
    initscr();
    raw();
    keypad(stdscr, TRUE);
    ct = get_wch(&unichar); /* read character */
    mvprintw(24, 0, "Key pressed is = %4x ", unichar);

    refresh();
    getch();
    endwin();
    return 0;
}

Testing code with GDB:

: UTF-8 get_wch. wint_t ( ).

Long: UTF-8 ncurses getch, / wchar_t :
