Description:
------------
In PHP 4.4.7 WDDX functions convert special characters(ISO 8859-1) to <char code='XX'/>. Apparently the encoding changed to UTF-8 in 4.4.7, while all our data and scripts are in ISO 8859-1.

(My company wants to upgrade to PHP version 4.4.7, we now still use 4.3.10-19 which doesn't have this bug.)


Reproduce code:
---------------
  $q = $_GET['q']; // incoming user question 'be?indiging verzekering'
   
  echo $q;

  //building WDDX packet

  $packet_id = wddx_packet_start("qxq_ask_command");
  wddx_add_vars($packet_id,"q");
  $packet = wddx_packet_end($packet_id);

  echo $packet; 

Expected result:
----------------
I expect the special character '?' to be 'as is' encoded in ISO 8859-1 inside the WDDX packet.

(...)<var name='q'><string>be?indiging verzekering</string></var>(...)



Actual result:
--------------
echo $q; // prints 'be?indiging verzekering' correctly

Inside the WDDX packet the '?' is converted to <char code='EB'/>

(...)<var name='q'><string>be<char code='EB'/>indiging verzekering</string></var>(...)
