If you want to get a string with all the 'normal' characters, this may be better:
$clean = preg_replace('/\W+/', '', $dirty);
\W is the opposite of \w and will match any character that is not a letter or digit or the
underscore character, plus it respects the current locale. Use [^0-9a-zA-Z_]+ instead of \W if you
need ASCII-only.
