    <para>
      <application>libidn</application> is a package designed for
      internationalized string handling based on the
      <ulink url="http://www.ietf.org/rfc/rfc3454.txt">Stringprep</ulink>,
      <ulink url="http://www.ietf.org/rfc/rfc3492.txt">Punycode</ulink> and
      <ulink url="http://www.ietf.org/rfc/rfc3490.txt">IDNA</ulink>
      specifications defined by the Internet Engineering Task Force
      (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.

            contains a generic Stringprep implementation that does Unicode
            3.2 NFKC normalization, mapping and prohibition of characters, and
            bidirectional character handling. Profiles for Nameprep, iSCSI, SASL
            and XMPP are included as well as support for Punycode and ASCII
            Compatible Encoding (ACE) via IDNA. A mechanism to define Top-Level
            Domain (TLD) specific validation tables, and to compare strings
            against those tables, as well as default tables for some TLDs are
            included.
