  <p>The Parser will call this method to report each chunk of
  character data.  SAX parsers may return all contiguous character
  data in a single chunk, or they may split it into several
  chunks; however, all of the characters in any single event
  must come from the same external entity, so that the Locator
  provides useful information.</p>
  
  <p>The application must not attempt to read from the array
  outside of the specified range.</p>
  
  <p>Note that some parsers will report whitespace using the
  ignorableWhitespace() method rather than this one (validating
  parsers must do so).</p>
  
  @param ch The characters from the XML document.
  @param start The start position in the array.
  @param length The number of characters to read from the array.
  @throws org.xml.sax.SAXException Any SAX exception, possibly
  wrapping another exception.
