      Defined in header<uchar.h>
      typedefunsignedchar char8_t;
      		(since C23)

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

      [edit]Example

      Run this code
      #include <stdio.h>#include <uchar.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 definitionprintf("%zu UTF-8 code units: [ ", str_sz);for(size_t n=0; n< str_sz;++n)printf("%02X ", str[n]);printf("]\n");}

      Possible output:

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