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.

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 aproach, two conversion functions exist
|
|
|
|
|
(:func:`unbound.idn2dname` and :func:`unbound.dname2idn`).
