In other words, XML is wrong technology to work with binary data, unless it is
encoded into
textual form (Base64 or alike).

XML 1.1 allows anything down to #1, but the current parser doesn't seem to
allow that. I guess
that should solve most of the problems here.
Specifically, TXMLDecodingSource.SkipUntil doesn't allow #1..#31 if FXML11Rules
is true, which I
think it should.
But the document prolog specified XML version 1.0,
so these characters are not allowed.
If of course Andrew creates the XML himself, he can specify 1.1 as the XML
version, then that may
well be a solution.
Yes, but changing the version still generates the same error, even though it
shouldn't
Note that the specs of 1.1 still say that
"The characters defined in the following ranges are also discouraged. They are
either control
characters or permanently undefined Unicode characters:
[#x1-#x8], [#xB-#xC], [#xE-#x1F], [#x7F-#x84], [#x86-#x9F], [#xFDD0-#xFDDF],
[#x1FFFE-#x1FFFF], [#x2FFFE-#x2FFFF], [#x3FFFE-#x3FFFF],
[#x4FFFE-#x4FFFF], [#x5FFFE-#x5FFFF], [#x6FFFE-#x6FFFF],
[#x7FFFE-#x7FFFF], [#x8FFFE-#x8FFFF], [#x9FFFE-#x9FFFF],
[#xAFFFE-#xAFFFF], [#xBFFFE-#xBFFFF], [#xCFFFE-#xCFFFF],
[#xDFFFE-#xDFFFF], [#xEFFFE-#xEFFFF], [#xFFFFE-#xFFFFF],
[#x10FFFE-#x10FFFF]."
So it would be wise to replace the characters with encoded data.
Michael.
It's true that it's not a good idea, but it should work at least :)
To my knowledge, XML 1.1 supports codes below 32 only in escaped forms. "" is valid in XML 1.1
but not in XML 1.0.
