Hehe, interesting idea, but it's not implemented that way. We don't
alter the XML data, except for the XML declaration.

I may write some patch, actually text mode will not be affected, becuase it's
text mode, and patch will fail if client encoding is "reacher" then server
(one possiblity in this situation is to XML-encode to client encoding, text-
rencode to server encoding)

But looking at code same thing could occur with binary recv. I saw there text
based XML conversion (it's altering XML in some way). According to doc I can
store XML in any encodign using binary mode.

I think if text conversion fails, then XML rewrite should occur, and all
unparsable character should be converted to XML entities...

Actually it's XML, not varchar with parsing :)
