   A variant based on your take:   
      
   size_t utf8width(char *s) {   
       size_t len = 0;   
       unsigned char c;   
      
       while ((c = (unsigned char)*s))   
           s += (c < 0x80) ? 1 :   
                (c < 0xE0) ? 2 :   
                (c < 0xF0) ? 3 : 4,   
           ++len;   
      
       return len;   
   }
