Description:
------------
Im inserting tables into my php document using the simple <?php 
include("price.php"); ?>  But it wont display the ? symbol on its own? 
It puts ? before every ? symbol?  appears like this £.

Is this a bug?

Reproduce code:
---------------
<?php include("price.php"); ?>


------
price.php

<table width="73%" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td width="7%"><table id="one-column-emphasis" summary="2007 Major IT Companies' Profit">
