But this is disallowed.  You can't have (say) &#6; because it's not a
valid XML character.  As many other people have mentioned, you really
need to base64 encode (or perhaps URI encode for small amounts) your
data.

    http://xml.com/axml/testaxml.htm

Which shows that:

Char ::= #x9 | #xA | #xD
         | [#x20-#xD7FF]
         | [#xE000-#xFFFD]
         | [#x10000-#x10FFFF] /* any Unicode character, excluding the
                               * surrogate blocks, FFFE, and FFFF. */
