uppercase A gets trimmed from beginning of ajax response
<p>If I make an ajax request and the response starts with uppercase A it gets trimmed. If it starts with lower a or any other uppercase char it's fine.</p>

<p>The ajax script</p>

<pre><code>$.ajax({
  type: "POST",
  url: "response.php",
  success: function(msg){
    alert(msg);
  }
});
</code></pre>

<p>PHP</p>

<pre><code>&lt;?php echo 'ABC'; ?&gt;
</code></pre>

<p>The response is BC, if the php code would be 'abc' the response would be abc</p>

<p>Note: I'm running apache2 on ubuntu server with php 5</p>
