I had to make my own such iterators in order to make xml_archives. These
are described in the serialization library under the misc/dataflow 
iterators.
I'm not sure what BE or LE refer to.  But I did adress UTF-16 and
UTF-8 was addressed with Ron Garcias UTF-8 codecvt facet.  This
is also documented in the misc section of the serializaiton library. A 
"complete
unicode solution" has been discussed here in some length.  The
requirements kept growing until the job was undoable.  Fortunately,
I don't think a "complete unicode solution" is required to make a
serviceable XML parser that we can build on.

great - when do you think you'll be done?
