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

DESCRIPTION
     The  idn2 tool converts DNS domains from UTF-8 to ASCII compatible encoding

     nationalized Domain Name (IDNA2008/TR46) format.

     Internationalized	Domain	Name (IDNA2008) convert STRINGS, or standard in-
     put.

     Command line interface to the Libidn2 implementation of IDNA2008.

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