Unlike the libUnbound, pyUnbound is able to handle IDN queries.

If we use unicode string in :meth:`unbound.ub_ctx.resolve` method, the IDN DNAME conversion (if it is necessary) is performed on background.

	:language: python

The :class:`unbound.ub_data` class contains attributes suffix which converts the dname to UTF string. These attributes have the '_idn' suffix.
Apart from this aproach, two conversion functions exist (:func:`unbound.idn2dname` and :func:`unbound.dname2idn`).
