NAME

       idn2 - Libidn2 Internationalized Domain Names conversion tool


SYNOPSIS

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


DESCRIPTION

       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.
