Remarks
Returns an IDNA instance which implements UTS #46. Returns an unmodifiable instance, owned by the caller. Cache it for multiple operations, and delete it when done. The instance is thread-safe, that is, it can be used concurrently.
UTS #46 defines Unicode IDNA Compatibility Processing, updated to the latest version of Unicode and compatible with both IDNA2003 and IDNA2008.
The worker functions use transitional processing, including deviation mappings, unless NONTRANSITIONAL_TO_ASCII or NONTRANSITIONAL_TO_UNICODE 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 ALLOW_UNASSIGNED option.
By default, the UTS #46 implementation allows all ASCII characters (as valid or mapped). When the 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.
