     * updated to the latest version of Unicode and compatible with both
     * IDNA2003 and IDNA2008.

     * is used in which case the deviation characters are passed through without change.
     *
     * Disallowed characters are mapped to U+FFFD.

     * Operations with the UTS #46 instance do not support the
     * UIDNA_ALLOW_UNASSIGNED option.
     *
     * By default, the UTS #46 implementation allows all ASCII characters (as valid or mapped).
     * When the UIDNA_USE_STD3_RULES option is used, ASCII characters other than
     * letters, digits, hyphen (LDH) and dot/full stop are disallowed and mapped to U+FFFD.
