'...the only difference between the two documents (in your example) will be that character references are expanded'
That's just the problem, i dont want the characters references to be expanded. I only want to get just the same xml output as was the xml input. Nothing more. Is it possible to do somehow ?

The trouble arises when you don't specify the encoding on the way out. Then Java will use whatever is set as the platform encoding, e.g., win1250. What normal text editors do with a UTF-8 file is really outside the scope here. You have to use a competent editor.
