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.
