They might be characters that are not legal in XML at all. See [1] which
says:
"Well-formedness constraint: Legal Character
Characters referred to using character references MUST match the
production for Char."
In XML 1.0 that's:
"Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] |
[#xE000-#xFFFD] | [#x10000-#x10FFFF] /* any Unicode
character,
excluding the
surrogate
blocks, FFFE,
and FFFF. */"
If you have any characters that don't fit this production, XML can't
represent them, escaped or not. XML 1.1 allows somewhat more, as I
recall.
