I think to do this we'd need something better than wcwidth.  See
appended.  Also as Eli points out, the terminal itself can do something
other than whatever wcwidth reports.

Tom

#define _XOPEN_SOURCE
#include <wchar.h>
#include <stdio.h>

#define C L"👉"

int main() {
  printf ("width = %d\n", wcswidth (C, wcslen (C)));
  printf ("of char = %d\n", wcwidth (C[0]));
  return 0;
}

bapiya. gcc -o q q.c
bapiya. ./q
width = -1
of char = -1
