Which one specifically are you thinking of? I'm pretty sure all
those control characters have a spot in the Unicode space and can
be properly encoded as UTF-8 (though I think even if they are
properly encoded, some of them are illegal in XML anyway).
If they appear in another form, it is invalid and/or needs a
charset conversion, which should be specified in the XML document
itself.
