/* This all should be lean enough to run these macros for every key on your board if you wanted.
 * That saids, I'm sure it could be improved upon, and fair warning this was stripped and modified
 * from my personal board's code, so it may have bugs relating to my poor copy-pasting skills or
 * my poor coding skills. However, it does run and appears to work as expected on my board.
 *
 * The benefit to using this method rather than unicode hex codes
 * or defining unicode keys and using tap_code instead of send_unicode_string is
 * that it allows for way more flexibility (and it's easy to copy paste the character you want!)
 * You can even use emoji and/or multiple characters!
 ***** NOTE: For multiple characters and some emoji you may need to increase the array size for the strings ****/
