SAX parsers are allowed to call the characters() method several times in a
row. Some parsers have a buffer of 8K (Crimson), others of 16K (Xerces) and
others can even call onCharacters() for every single characters! Thus we need
to accumulate the characters in a buffer before we process them. This filter
does exactly this.
