I was doing some light reading the other day and found the following comment in lib/weblib.php
// When we move to PHP 5.4 as a minimum version, change ENT_QUOTES on the
|
// next line to ENT_QUOTES | ENT_HTML5 | ENT_SUBSTITUTE, and remove the
|
// 'UTF-8' argument. Both bring a speed-increase.
|
return preg_replace('/&#(\d+|x[0-9a-f]+);/i', '&#$1;', htmlspecialchars($var, ENT_QUOTES, 'UTF-8'));

As of Moodle 2.7 PHP 5.4 is required so this change should be made to 2.7 and 2.8dev. I don't know what it means, but hope somebody remembers it.
