Bug description: WDDX does not work anymore
Description:
------------
I have a small cms which works over year, but with the upgrade from
php-4.4.2 on Debian Sarge to php-4.4.4 wddx does not work anymore. I go
back to the old version and it works. I used the same configuration script
for both php versions.
The problem is, its not easy for me as an admin to find the right portion
of code, but tried to reproduce this on my mac, not linux, because its a
production machine. i got malformed wddx output with my show() method. on
my linux machine the wddx output was empty.
i hope it helps and i made no mistakes :)
Reproduce code:
---------------
<?php
function ideacms_isutf8( $pString, $pComp = false ) {/*{{{*/
if( !$pComp ) {
return preg_match( '%^(?:

overlongs
| [\xE1-\xEC\xEE\xEF][\x80-\xBF]{2} # straight
