Let's be clearer:
1. libxml++ takes UTF8 in its API.
2. libxml++ gives UTF8 in its API.
3. libxml++ can parse documents in any encoding, if the encoding is
properly declared in the document.

libxml++ uses UTF8 in its API because UTF8 is the encoding that can
represent anything.

If you want to convert, or manipulate, UTF8 without Glib::ustring, the I
can recommend the glib g_utf8_* functions that Glib::ustring uses.
However, I think you will be making your life more difficult than if you
just use Glib::ustring.
