I have a few simple questions, because I got confused reading all difference responses.
1) If I have an xml with prolog: <?xml version="1.0" encoding="utf-8" ?>
and I'm going to unmarshall it with Java (for example: JaXB). I suppose, that I can't put CROSS OF LORRAINE (http://www.fileformat.info/info/unicode/char/2628/index.htm) inside, but I can put "\u2628", correct?
2) I've also heard that UTF-8 doesn't contain it, but anything in Unicode can be saved with encoding UTF-8 (or UTF-16), and here is an example from this page:
UTF-8 (hex) 0xE2 0x98 0xA8 (e298a8)
Is my reasoning correct? Can I use this form and put it in the xml with utf-8 encoding?
