> It's illegal to include a non-visible control character in XML, even as a character entity.  e.g. "&amp;#x0;" is illegal in XML, even though it's semantically meaningful.
> http://www.w3.org/TR/1998/REC-xml-19980210#charsets
> Disturbingly, Java's XML serializer will cheerfully print out &amp;#x0; despite the fact that it will refuse to parse that entity.
> As a workaround, for 2.4.2 we're deliberately doublly XML-escaping non-visible control characters, printing them as "&amp;amp;#x0;" instead of "&amp;#x0;" like they're supposed to be.  That's better than any alternative I can think of (e.g. throwing the characters away in test results, replacing them with a "?" character).
