I am still not sure that you can not put a representation of the character \0 inside an XML, but if it were possible, the natural representation would be "�" (without the quotes) Why not just use it?
Have you tried it? It's not a valid entity, using it means your XML is not well-formed. It doesn't matter whether you say � or � (the decimal and hexadecmial forms are exactly equivalent - but 0 is still not a validnumerical entity.)
That's the solution for '\0'. Its just not obvious to me that that is the whole problem. What about '\01' ? or non-printable characters in general? Does the encoding come into play? How? These are questions I don't currently have an answer to.
As long as you can read the same data back and restore the same sequence of bytes it doesn't really matter. jon
