IDNA 2008 encoder/decoder.

*uts_46* is a ``bool``. If True, apply Unicode IDNA compatibility processing as described in Unicode Technical Standard #46 (http://unicode.org/reports/tr46/). If False, do not apply the mapping. The default is False.

*transitional* is a ``bool``: If True, use the "transitional" mode described in Unicode Technical Standard #46. The default is False.

*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 names, e.g. a name with starting with "_sip._tcp." and ending in an IDN suffix which would otherwise be disallowed. The default is False.

*strict_decode* is a ``bool``: If True, then IDNA2008 checking is done when decoding. This can cause failures if the name was encoded with IDNA2003. The default is False.
