 *    ©
 *   © ©
 *  ©   ©
 * © © © ©
 * Note that the © symbol may be displayed incorrectly at the console so you may need to change the console character encoding to UTF-8 and assign a Unicode-friendly font in the console.
 * Note also, that under old versions of Windows the © symbol may still be displayed incorrectly, regardless of how much effort you put to fix it. */
