## 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.
