The encoding, if it is declared, is in the very beginning of
the xml file, it shoud not be much work to pick it out.

Maybe a FilterStream/FilterReader subclass that locks for
the <?xml ... ?> line and remebers the encoding declared.

This way people that worry about the encoding can wrap their
incomming xml in this "EncodingFinderStream" before
handing it to the SAXBuilder.

Woud cost a little bit of cpu performance to do this
since all reads will have an extra fuction call.

I woud asume the stream woud be used for a single
XML-file only since SAXBuilder looks for the EOF.


If I have time I'll write one and contrib it, unless someone
commes up with a reason it is a very bad idea.
