   Smallest Unicode test I can manage. Might prove handy in some contexts:   
      
   #include    
   #include    
   #include    
      
   int got_unicode(void){   
       char *l = setlocale(LC_CTYPE,"");   
       return (l && strstr(l,"UTF-8"));   
   }   
      
   #define U(uni, asc) (got_unicode() ? (uni) : (asc))   
      
   int main(void){   
       printf("%s\n", U("Unicode OK: ✓", "No Unicode."));   
       return 0;   
   }
