idncheck(1) General Commands Manual idncheck(1) NAME idncheck - check an internationalized domain name SYNOPSIS idncheck [options..] name DESCRIPTION idncheck command checks an internationalized domain name. It tries to con- vert name to A-labels with various checks defined by IDNA2008-Protocol. If the given name is a valid internationalized domain name, idncheck out- puts the message: passed. to standard error and returns with exit code 0. Note that also traditional ASCII domain names are considered valid. If the name is not valid, it outputs the reason (e.g. ``invalid encoding'') 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 er- ror and then returns with exit code 3. Unless -noconf (or -C) option is given, idncheck reads a configuration file (/usr/local/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 argument. Any of the following encoding names can be recognized. * Any encoding names which iconv_open() accepts * Punycode * UTF-8 * 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 (/usr/local/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 behavior. -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 protocol. ctxolitecheck CONTEXTO code point check for domain name lookup protocol. bidicheck Bidi check. idnconvconversion to Punycode lencheck label length check rtcheckround trip check -localcheck file, -e file Also perform code point check using file. Using the local check fea- ture, you can check whether a domain name consists of code points al- lowed 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 immedi- ately. -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.

It is better to explicitly specify it using -in option. Sep 21, 2012 idncheck(1)
