Fake good sorting for en-US

sort.php

<?php

/*
 * In 2013, locale-based sort is still broken or headache-inducing on many machines, and 
 * POSIX or C locales are the unassailable default in a shocking number of places. (For a 
 * fun exercise, try relying on LC_COLLATE for sorting in OS X.)
 *
 * This is a shameful PHP-based hack that mimics proper sorting for English using iconv 
 * transliteration. If doing things the WRONG WAY offends you, avert your eyes. However, 
 * this has worked for me in a pinch when I don’t have time to track down a box that has 
 * its i18n together.
 *
 * Short version: Sort correctly with “special characters.”
