*allow_pure_ascii* is a ``bool``. If True, then a label which
consists of only ASCII characters is allowed. This is less
strict than regular IDNA 2008, but is also necessary for mixed

in an IDN suffix which would otherwise be disallowed. The

``(relation, order, nlabels)``.
*relation* describes the relation ship between the names,
and is one of: ``dns.name.NameRelation.NONE``,
``dns.name.NameRelation.SUPERDOMAIN``, ``dns.name.NameRelation.SUBDOMAIN``,
``dns.name.NameRelation.EQUAL``, or ``dns.name.NameRelation.COMMONANCESTOR``.
*order* is < 0 if *self* < *other*, > 0 if *self* > *other*, and ==
0 if *self* == *other*. A relative name is always less than an
absolute name. If both names have the same relativity, then
the DNSSEC order relation is used to order them.
*nlabels* is the number of significant labels that the two names
have in common.
Here are some examples. Names ending in "." are absolute names,
those not ending in "." are relative names.

*file* is the file where the name is emitted (typically an
io.BytesIO file). If ``None`` (the default), a ``bytes``
containing the wire name will be returned.
*compress*, a ``dict``, is the compression table to use. If
``None`` (the default), names will not be compressed. Note that
the compression code assumes that compression offset 0 is the
start of *file*, and thus compression will not be correct
if this is not the case.
*origin* is a ``dns.name.Name`` or ``None``. If the name is
relative and origin is not ``None``, then *origin* will be appended
to it.
*canonicalize*, a ``bool``, indicates whether the name should
be canonicalized; that is, converted to a format suitable for
digesting in hashes.
Raises ``dns.name.NeedAbsoluteNameOrOrigin`` if the name is
relative and no origin was provided.

t|j�� t|�S )a� Convert unicode text into a Name object.
Labels are encoded in IDN ACE form according to rules specified by
the IDNA codec.
*text*, a ``str``, is the text to convert into a name.
*origin*, a ``dns.name.Name``, specifies the origin to
append to non-absolute names. The default is the root name.
*idna_codec*, a ``dns.name.IDNACodec``, specifies the IDNA
encoder/decoder. If ``None``, the default IDNA 2003 encoder/decoder
is used.
Returns a ``dns.name.Name``.
