    (IETF) Internationalized Domain Names (IDN) working group, used for
    internationalized domain names. This is useful for converting data from the
    system's native representation into UTF-8, transforming Unicode strings
    into ASCII strings, allowing applications to use certain ASCII name labels
    (beginning with a special prefix) to represent non-ASCII name labels, and
    converting entire domain names to and from the ASCII Compatible Encoding
    (ACE) form.</para>
