I suggest you catch the exception and take a look at the error message.
Without that, it will be impossible to diagnose the problem. Start with
catching SAXParseException, because that's probably what's being thrown.

The two bytes C3 84 in UTF-8 encode the Unicode character U+00C4, Latin
Capital Letter A With Diaeresis, or capital A with an umlaut. Is that the
character you're expecting?

What do you mean by "if i return the same character created from the
Xerces-C++ DOM?" How did you create this instance? Did you parse it? If
not, that DOM instance probably isn't relevant to the discussion. Do you
mean you are serializing an instance of the DOM, and you are getting those
two characters? If that's the case, you have an encoding problem, because,
in UTF-16, you are getting U+00C3 (Latin Capital Letter A With Tilde) and
U+0132, which is a control character.
My understanding of VB, which is extremely limited, is that strings are
encoded in UCS-2, not UTF-8. You may have a problem with parsing a
document which contains an encoding declaration asserting the document is
in UTF-8, when it really is UCS-2.
