       idn2 - Libidn2 Internationalized Domain Names conversion tool


       idn2 [OPTION]... [STRINGS]...


       idn2  tool  converts  DNS  domains from UTF-8 to ASCII compatibile encoding (ACE) form, as
       used in the DNS protocol.  The  encoding  format  is  the  Internationalized  Domain  Name
       (IDNA2008/TR46) format.

       All input strings are expected to be encoded in the locale charset.

       To  process  a  string  that  starts with -, for example -foo, use -- to signal the end of
       parameters, as in idn2 --quiet -- -foo.

       Mandatory arguments to long options are mandatory for short options too.

       -h, --help
              Prints help and exits.

       -V, --version
              Prints version and exits.

       -d, --decode
              Decode an ACE name according to IDNA2008.

       -l, --lookup
              Encode to ACE according to IDNA2008 (the default).

       -r, --register
              Registers a label.

       -T, --tr46t
              Enable TR#46 transitional processing.

       -N, --tr46nt
              Enable TR#46 non-transitional processing (default).

              Disable TR#46 processing.

              Enable STD3 ASCII rules.

              Prints debugging information.

              Silent operation.
