locale and ISO 2022 support for Unicode terminals

 Luit is a filter that can be run between an arbitrary application and a
 UTF-8 terminal emulator. It will convert application output from the
 locale's encoding into UTF-8, and convert terminal input from UTF-8
 into the locale's encoding.
 .
 This is version 2.0 of luit, which can use encoding information from
 either the font-encoding data-files in the "xfonts-encodings" package,
 or the standard locale support in the C runtime library.
