This function converts Unicode domain name from IDNA ASCII-compatible format to plain Unicode, encoded in UTF-8.

domain: Domain to convert in IDNA ASCII-compatible format.
options: Conversion options - combination of IDNA_* constants (except IDNA_ERROR_* constants).
variant: Either INTL_IDNA_VARIANT_2003 for IDNA 2003 or INTL_IDNA_VARIANT_UTS46 for UTS #46.
idna_info: This parameter can be used only if INTL_IDNA_VARIANT_UTS46 was used for variant. In that case, it will be filled with an array with the keys 'result', the possibly illegal 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', which is an int representing a bitset of the error constants IDNA_ERROR_*.
