I prefer serializeing in UTF-8 regardless of the input encoding.
It is not impossible but painful to get the BOM and the XML
declaration with existing XML processors.

If the serialization had to encode in non-UTF encoding, it had
to check whether each character could be encoded in that
encoding.  This check is hard to implement in Java.


You have to specify also output encoding of string type results
of XPath.  A string in XPath is character sequence, not octet
sequence.
