history

Project history and usage

cocot is a terminal code-conversion utility whose name expands to COde COnverter on Tty. It sits in a terminal workflow to translate character encodings for programs and remote sessions.

Project history

The upstream ChangeLog records a first release in 2002, early work around EUC-JP, Shift_JIS/CP932, ISO-2022-JP decoding, and later Unicode and East Asian Width updates. The project source moved to GitHub in 2009.

Adoption history

The package appears in Unix package-manager culture as a small compatibility tool for terminals that still need Japanese legacy encoding conversion. The input records Homebrew, Fedora/dnf, and MacPorts package names.

How it is used

Users run cocot around tty programs when the process encoding and terminal encoding differ, especially in CJK terminal environments.

Why package nerds care

cocot is interesting as a compact example of terminal-era encoding glue: small C code, iconv-oriented behavior, and long-tail packaging value for workflows that modern UTF-8 defaults did not fully erase.

Timeline

2002: First release recorded in the upstream ChangeLog.
2004: Unicode support and patch merging appear in NEWS and ChangeLog.
2008: East Asian Width table update and --help/--version options appear in NEWS.
2009: ChangeLog records the source being pushed to github.com/vmi/cocot.
2017: Build scripts and warning fixes are recorded in the ChangeLog.

Related projects

iconv and terminal emulators occupy the same problem space for character-set conversion and display behavior.
