C99 wprintf UTF-16 not aligned

Question

I am writing a C99 console program, using UTF-16, and I need to align the characters, however, using wprintf, the characters are not the same width.

#include <stdio.h>
#include <stdlib.h>
#include <locale.h>
#include <fcntl.h>
#include <io.h>
int main() {
    _setmode(_fileno(stdout), _O_U16TEXT);

    wprintf(L"%-10.1ls%ls\n", L"\u2654", L"hello");
    wprintf(L"%-10.1ls%ls\n", L"h", L"hello");
}

♔         Hello
h         Hello

I would like to be able to align perfectly the second text (here 'hello').
