I tested this on sdk-1.30.0-64bit. I wrote a sample program below:
#include <stdio.h>
#include <string>
#include <clocale>
using namespace std;
int main(int argc, const char * argv[])
{
// insert code here...
printf("Hello, World!\n");
char* locale = setlocale(LC_ALL, NULL);
wchar_t smallE = L'é';
wchar_t bigE = towupper(smallE);
return 0;
}
I tested this on XCode and the result is the same as Visual Studio. I then
ran the code against sdk 1.34.1 and emscripten-tag-1.34.3-64bit and both
versions return the uppercase É which differs from both XCode and Visual
Studio.
