      Defined in header<uchar.h>
      typedefuint_least32_t char32_t;
      		(since C11)

      char32_t is an unsigned integer type used for 32-bit wide characters and is the same type asuint_least32_t.

      [edit]Notes

      On any given platform, by the definition ofuint_least32_t, the width of typechar32_t can be greater than 32 bits, but the actual values stored in an object of typechar32_t will always have a width of 32 bits.

      [edit]Example

      Run this code
      #include <stdio.h>#include <uchar.h> int main(void){const char32_t wc[]= U"zß水🍌";// or "z\u00df\u6c34\U0001f34c"constsize_t wc_sz=sizeof wc/sizeof*wc;printf("%zu UTF-32 code units: [ ", wc_sz);for(size_t n=0; n< wc_sz;++n)printf("%#x ", wc[n]);printf("]\n");}

      Possible output:

      5 UTF-32 code units: [ 0x7a 0xdf 0x6c34 0x1f34c 0 ]
