NAME
       idncheck - check an internationalized domain name

SYNOPSIS
       idncheck [options..] name

DESCRIPTION
       idncheck  command checks an internationalized domain name.  It tries to
       convert name to A-labels with various checks defined by IDNA2008-Proto-
       col.

       If  the  given  name is a valid internationalized domain name, idncheck
       outputs the message:

           passed.

       to standard error and returns with exit code 0.  Note that also  tradi-
       tional ASCII domain names are considered valid.

       If  the name is not valid, it outputs the reason (e.g. ``invalid encod-
       ing'') to standard error and returns with exit code 2.  If an  internal
       error  such as memory exhaustion is caused, idncheck outputs the reason
       to standard error and then returns with exit code 3.

       Unless -noconf (or -C) option is given, idncheck reads a  configuration
       file  (/etc/idn2.conf,  ~/.idn2rc or a file specified by an option) and
       performs conversions according to the parameters specified in the file.

OPTIONS
       -in in-code, -i in-code
           Specify the encoding name of the domain name specified as an  argu-
           ment.  Any of the following encoding names can be recognized.

           o Any encoding names which iconv_open() accepts

           o Punycode

           o UTF-8

           o Any  alias  names  for  the  above, defined by the encoding alias
             file.

           The encoding defaults to the  value  of  the  environment  variable
           ``IDN_LOCAL_CODESET''  or, if it is not set, an encoding determined
           from the locale information.

       -conf file, -c file
           Specify the path of idnkit configuration file.  If  not  specified,
           the  default  path (/etc/idn2.conf or ~/.idn2rc) unless -noconf (or
           -C) option is specified.

       -noconf, -C
           Suppress reading a configuration file.

       -registration, -g (default)
           Use domain name registration protocol.  This is the default  behav-
           ior.

       -lookup, -l
           Use domain name lookup protocol.

       -nomap, -M
           Don't  perform  the  ``map''  action.   This is the same as ``-skip
           map''.

       -skip action,...
           Skip actions. the following action names are recognized:

           map    mappings

           asclower
                  convert ASCII uppercase letters to lowercase

           rtconv conversion from Punycode to Unicode for round trip check

           prohcheck
                  prohibited code point check

           unascheck
                  unassigned code point check

           nfccheck
                  NFC conformance check

           prefcheck
                  ACE prefix check

           hyphcheck
                  hyphen check

           combcheck
                  combining character check

           ctxjcheck
                  CONTEXTJ code point check

           ctxocheck
                  CONTEXTO code point check for domain name registration  pro-
                  tocol.

           ctxolitecheck
                  CONTEXTO code point check for domain name lookup protocol.

           bidicheck
                  Bidi check.

           idnconv
                  conversion to Punycode

           lencheck
                  label length check

           rtcheck
                  round trip check

       -localcheck file, -e file
           Also  perform  code  point check using file.  Using the local check
           feature, you can check whether  a  domain  name  consists  of  code
           points  allowed  by  a  particular registry.  The format of file is
           explained in idn_setlocalcheckfile(3).

       -quiet, -q
           Suppress a result message; yield exit status only.

       -test, -t
           Print which language, input encoding and output  encoding  will  be
           chosen  if  the  same  arguments are gievn to the command, and then
           quit immediately.

       -version, -v
           Print version information and quit.

       -help, -h
           Print help and quit.

LOCAL ENCODING
       idncheck guesses local encoding from locale and environment  variables.
       See the ``LOCAL ENCODING'' section in idn2.conf(5) for more details.

BUGS
       The automatic input-code selection depends on your  system,  and  some-
       times it cannot guess or guess wrong.  It is better to explicitly spec-
       ify it using -in option.
