title: XML validation error - PCData invalid char value 3
body: <p>I have opened an XML file in chrome browser, and I keep getting the following error:</p>
  
  <pre><code>error on line 1 at column 18267861: PCDATA invalid Char value 3
  </code></pre>
  
  <p>What's wrong? I have downloaded the file and checked the column in command line:</p>
  
  <pre><code>cat file.xml | head -c 18267855 | tail -c 10 | hexdump -C
  
  72 c4 99 c4 87 20 77 20  6c 65
  </code></pre>
  
  <p>It shows me that the character at the given position is space (0x20). What's wrong?</p>
