Are you sure it really is a QUESTION MARK, or is it a bullet character and the program you use to view the document either uses the wrong encoding, e.g. UTF-8 vs. ISO-8859-1, or could it be that the font you use doesn't have a glyph for the bullet character and displays it as a question mark.

I don't understand the question. Does accuracy mean using entitiy references? If determing which characters you have in your input XML documents, you should probably get an editor/viewer that loads the document using the correct character encoding and also can display non-ASCII characters correctly.
