     * 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,

     * is used in which case the deviation characters are passed through without change.
     *

     * 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).
