About:
Luit is a utility that acts as a filter to convert terminal input and output between a specified character set and UTF-8. It enables legacy applications that do not support Unicode to run correctly on modern UTF-8 based terminal emulators. This ensures compatibility and proper text rendering for older software in contemporary environments.

Key Features:

Character set conversion between legacy encodings and UTF-8
Acts as a transparent filter for application compatibility
Supports various legacy character sets including ISO 8859 and EUC
Maintains terminal control sequences during conversion

Use Cases:

Running legacy applications on modern Linux or macOS terminals
Displaying non-UTF-8 text correctly in a UTF-8 environment
Bridging compatibility for software that lacks native Unicode support

Alternatives:

iconv – Luit is designed for real-time terminal I/O, whereas iconv is a command-line utility for converting text files.
expect – Luit specifically handles character encoding translation, while expect is a broader tool for automating interactive applications.
