sudofont should replace both Nintendo's PUA characters and the emoji with the Nintendo-style glyphs

[sudofox]

This way, we can have the DSi style emoji on the site while still having the right 'equivalent' ones show up on OpenGraph, sharing, Google, and so on.

Right now I switched it to this:

<?php

// new version of stringToEmoji to use actual globally-supported emoji substitutes

function stringToEmoji ($string) {

$nintendoPUA = [ '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '//', '/󺜀/', '/󺜀/' ];

$replacementCharacters = ['😃', '😠', '😔', '😑', '☀', '☁', '☔', '⛄', '✉', '📱', '⏰', 'Ⓐ', 'Ⓑ', 'Ⓧ', 'Ⓨ', 'Ⓛ', 'Ⓡ', '➕', '♠', '♦', '♥', '♣', '❗', '❓', '➡', '⬅', '⬆', '⬇', '✕', '🐸' ];

return  preg_replace($nintendoPUA, $replacementCharacters, $string);

}

replacing the other characters with the Sudofont glyphs will restore the DSi symbols to Theatre whilst making them show up properly everywhere else.
