The test case that I sent uses UTF-8 encoding.
Here's another test case, that uses GB18030 (supposedly supported
since Cygwin 3.5.0). It fails as well, in line 26.
On glibc systems, this test works.
#include <assert.h>
#include <locale.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <uchar.h>
#include <wchar.h>
int main ()
{
assert (setlocale (LC_ALL, "zh_CN.GB18030") != NULL);
mbstate_t state;
memset (&state, 0, sizeof (state));
char32_t uc = 0xDEADBEEF;
size_t bytes;
/* \224\071\311\067 = U+0001F403 */
bytes = mbrtoc32 (&uc, "\224", 1, &state);
assert (bytes == (size_t)-2);
bytes = mbrtoc32 (&uc, "\071", 1, &state);
assert (bytes == (size_t)-2);
bytes = mbrtoc32 (&uc, "\311", 1, &state);
assert (bytes == (size_t)-2);
bytes = mbrtoc32 (&uc, "\067", 1, &state);
assert (bytes == 1);
assert (uc == 0x0001F403);
}
/* Works in: glibc
Fails in: Cygwin 3.5.3
*/
