8Automatic IDN DNAME conversion
9-------------------------------
10
11If we use unicode string in :meth:`unbound.ub_ctx.resolve` method,
12the IDN DNAME conversion (if it is necessary) is performed on background.

20IDN converted attributes
21------------------------
22
23The :class:`unbound.ub_data` class contains attributes suffix which converts
24the dname to UTF string. These attributes have the ``_idn`` suffix.
25
26Apart from this approach, two conversion functions exist
27(:func:`unbound.idn2dname` and :func:`unbound.dname2idn`).
