Trying to use htmlspecialchars() on a string containing &#xHEX; characters e.g. £
With double encode set to false, it still converts the & to &

Reproduce code:
$str = "£ one & two";
$out = htmlspecialchars($content, ENT_COMPAT, 'UTF-8', FALSE);
echo $out;

Expected result:
£ one & two

Actual result:
£ one & two

obviously that should have been $out = htmlspecialchars($str, ENT_COMPAT, 'UTF-8', FALSE);

It's just that the function does not understand the hex entities. :)

Thanks for the prompt reply. I understood though that this function with double encode arg set to false would not act on _any_ existing html entities.
Is there a reason why it does not recognize these codes, or is it an oversight/bug?
