.. _example_idna:
=================================================
Internationalized domain name support
=================================================
Unlike the libUnbound, pyUnbound is able to handle IDN queries.
.. literalinclude:: example7-1.py
:language: python
If we use unicode string in :meth:`unbound.ub_ctx.resolve` method, the IDN DNAME conversion (if it is necessary) is performed on background.
.. literalinclude:: example7-2.py
: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`).
