  Irrealistic with libxml, libxml-1.8.12 and libxml2 both use UTF8
for the internal representation in memory. Libxml has not idea
of a locale, it's an XML app not a GUI one.

  Libxml1 can't do this, this is doable with libxml2 but the internal
tree content will be in UTF8 anyway.

  No upon loading everything will be converted to UTF8, you have a single
representation independant of the charset or locale.

  No you can't, it won't do it. There is no support for it.
