according to the comment of the source code the more() function in
java/org/jivesoftware/openfire/net/MXParser.java is to make sure each individual
character is a valid XML character. But this function is keeping throw exception
if some chinese UTF-8 character(eg. ) is included in the xml stanza.
I wonder if I can simply disable this method to allow all utf-8 character been
included in the xml stanza.
