Using PHP I want to use regex to convert ¬" to ' (an apostrophe)

I don't want to use the actual characters â¬" in my regex because they could get corrupted by character set changes.  Instead I need their numerical values.

I think you can use \xnn where nn is the hexadecimal value of the char, or \unnnn where nnnn is the unicode value.

How can I use the hexadecimal values with preg_replace?
<?php
$str='Replace this with an apostrophy: â¬" ';
$str = preg_replace('|\u00e2\u00e2\u2122|',"'",$str);
echo $str;
?>
