Subject: Re: [Boost-users] How does boost.serialization do with BOM intext/xmlfiles

This is news to me.
the wide character text/xml archives use UTF-8. They do this
by creating a stream with the uft_codecvt_facet. I used
this factet, it worked great and I moved on. So you're way
ahead of me on this.
This would probably be easy to address in the xml_iarchive code
or perhaps the xml_grammar - but, as I said, I don't know
anything about it.
