QEmacs is a small but powerful text editor with an Emacs-like interface.
Designed for tasks such as embedded development and debugging, it combines a lightweight footprint with features often associated with much larger editors. It supports editing huge files efficiently, offers full Unicode handling, and includes both terminal and X11 interfaces.
This is free and open source software.

- Provides full Unicode support, including multiple character sets and bidirectional text editing.
- Includes shell and compile modes with VT100 terminal emulation and colorized error parsing.
- Offers binary and hexadecimal editing modes for patching files in place.
