You can convert from UTF-16 to UTF-8 using g_utf16_to_utf8() (for which
purpose you will need to include glib/gunicode.h).  You will need to
call g_free() on the return value after putting it in a Glib::ustring
object.

You can go the other way with g_utf8_to_utf16().  It returns an array of
type gunichar2, which is typedef'ed to guint16, also requiring to be
g_free'd when you have finished with it.
