10.2 Description

idn allows internationalized string preparation (‘stringprep’), encoding and decoding of punycode data, and IDNA ToASCII/ToUnicode operations to be performed on the command line.

If strings are specified on the command line, they are used as input and the computed output is printed to standard output stdout. If no strings are specified on the command line, the program read data, line by line, from the standard input stdin, and print the computed output to standard output. What processing is performed (e.g., ToASCII, or Punycode encode) is indicated by options. If any errors are encountered, the execution of the applications is aborted.

All strings are expected to be encoded in the preferred charset used by your locale. Use --debug to find out what this charset is. You can override the charset used by setting environment variable CHARSET.

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