A parser is not ever allowed to change the numeric value of a character.
The best thing is to avoid using numeric character entities and just encode
the character as a UTF-8 byte sequence (or the appropriate character
sequence for the charset in effect).  That way, XML parsers and serializers
are free to translate the character as appropriate for the charset in
effect.
Conforming parsers deliver characters in Unicode. The result is the same 
whether a character is encoded as a UTF-8 sequence or a character reference.

Subject: utf-8 characters problem

Hi,
when I parse the xml document (with xerces 2.6.2) which has in xml 
declaration specified utf-8 encoding and which contains utf-8 characters 
in character reference form &#xxxx;
the parser replaces these characters  with ascii characters. For some 
characters is ok but for instance InvisibleTimes change for some 
incorrect strange character sentese.
I'd like to know if is possible to prohibit changing characters from 
char. ref. form ? Or does it exist some recommendation how to treat with 
these characters.

Here is a piece of my 'problematic' xml document
<?xml version="1.0" encoding="UTF-8"?>
<mathDoc>
<p>Factorise the following quadratic expression:
        <math>
          <mrow>
            <msup>
              <mrow>
            <mi>x</mi>
              </mrow>
              <mrow>
            <mn>2</mn>
              </mrow>
            </msup>
            <mo>&#x002b;</mo> <!-- replaces with character + -->
            <mi>p</mi>
            <mo>&#x2062;</mo>   <!-- here is InvisibleTimes -->
                    <mi>x</mi>
            <mo>&#x002b;</mo>  <!-- replaces with character + -->
            <mi>q</mi>
          </mrow>
        </math>
</mathDoc>
Thanks so much
Jakub
