Bug description:
  We had a report of a Mahara-generated Leap2a file that caused this
  crash stack upon attempting to import it:

  [WAR] 38 (import/leap/lib.php:126) simplexml_load_file(): /home/aaronw/dataroot/mahara/temp/import/admin-1438900425/extract/leap2a.xml:1808: parser error : PCDATA invalid Char value 11
  Call stack (most recent first):

      log_message("simplexml_load_file(): /home/aaronw/dataroot/mahar...", 8, true, true, "/home/aaronw/www/mahara/htdocs/import/leap/lib.php", 126) at /home/aaronw/www/mahara/htdocs/lib/errors.php:441
      error(2, "simplexml_load_file(): /home/aaronw/dataroot/mahar...", "/home/aaronw/www/mahara/htdocs/import/leap/lib.php", 126, array(size 2)) at Unknown:0

  Upon investigation it turned out that the leap2a XML file had a
  Vertical Tab character (ASCII x0A) in one of the page titles. There is
  a whole range of ASCII control characters that will cause a parser
  error in SimpleXML, and if they're placed in a Mahara page title, they
  will be included in the output of the Leap2a file, which will cause
  Mahara to crash when it attempts to import the file.
