char32_t

Defined in header <uchar.h> 
typedef uint_least32_t char32_t;
+		 (since C11)

char32_t is an unsigned integer type used for 32-bit wide characters and is the same type as uint_least32_t.

+

Notes

On any given platform, by the definition of uint_least32_t, the width of type char32_t can be greater than 32 bits, but the actual values stored in an object of type char32_t will always have a width of 32 bits.

+

Example

#include <stdio.h>
+#include <uchar.h>
+ 
+int main(void)
+{
+    const char32_t wc[] = U"zß水🍌"; // or "z\u00df\u6c34\U0001f34c"
+    const size_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 ]
