The program is so small I don't need github, I apologise.
If you make st window 1 row high and 9 columns wide, so string
"😍😍😍😍x" should fill whole window, last emoji gets cut on half.

gcc st_bug.c -DNCURSES_WIDECHAR=1 -lncursesw

#include <curses.h>
#include <locale.h>
int main() {
    setlocale(LC_ALL, "");
    initscr();
    printw("😍😍😍😍x");
    getch();
    endwin();
    return 0;
}

For the same string without curses there is no problem, so probably is
not st problem, but in other terminals I don't get such behavior.

#include <stdio.h>
int main() {
    printf("😍😍😍😍x");
    int c = getchar();
    return 0;
}

Andrej
