char8_t 是一个无符号整数类型，用于 UTF-8，与 unsigned char 类型相同。
[编辑] 示例
#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");
}可能的输出
11 UTF-8 code units: [ 7A C3 9F E6 B0 B4 F0 9F 8D 8C 00 ]
