I believe the following should reproduce it:

1. Use the following C source file

#include <stdlib.h>
#include <string.h>
#include <locale.h>

int main()
{    
	char *s6 = "Ｕｎｉｃｏｄｅ! 🅤🅝🅘🅒🅞🅓🅔‽ 🇺‌🇳‌🇮‌🇨‌🇴‌🇩‌🇪! 😄 The very name strikes fear and awe into the hearts of programmers worldwide. We all know we ought to “support Unicode” in our software (whatever that means—like using wchar_t for all the strings, right?). But Unicode can be abstruse, and diving into the thousand-page [Unicode Standard](http://www.unicode.org/versions/latest/) plus its dozens of supplementary [annexes, reports](http://www.unicode.org/reports/), and [notes](http://www.unicode.org/notes/) can be more than a little intimidating. I don’t blame programmers for still finding the whole thing mysterious, even 30 years after Unicode’s inception.";
    
    printf("%s\n", s6);
    
	return 0;
}

2. Try to watch s6 in the Watch window
