.. _example_idna:
Internationalized domain name support
=====================================
Unlike the libUnbound, pyUnbound is able to handle IDN queries.
Automatic IDN DNAME conversion
-------------------------------
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
IDN converted attributes
------------------------
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 approach, two conversion functions exist
(:func:`unbound.idn2dname` and :func:`unbound.dname2idn`).
