char8_t

char8_t is an unsigned integer type used for UTF-8 and is the same type as unsigned char .

Example

#include <uchar.h>
#include <stdio.h>
 
int main(void)
{
    char8_t str[] = u8"zß水🍌"; // or "z\u00df\u6c34\U0001f34c"
    size_t str_sz = sizeof str; // sizeof *str == 1 by definition
    printf("%zu UTF-8 code units: [ ", str_sz);
    for (size_t n = 0; n < str_sz; ++n)
        printf("%02X ", str[n]);
    printf("]\n");
}

11 UTF-8 code units: [ 7A C3 9F E6 B0 B4 F0 9F 8D 8C 00 ]
