domain-
Domain to convert in an IDNA ASCII-compatible format.
flags-
Conversion options - combination of IDNA_* constants
(except IDNA_ERROR_* constants).

result of the transformation,
'isTransitionalDifferent', a boolean indicating
whether the usage of the transitional mechanisms of UTS #46 either has
or would have changed the result and 'errors',

constants IDNA_ERROR_*.
