- Full Unicode support for nearly all human languages and their scripts.
- Complete built-in documentation, including a tutorial for new users.
- A large number of extensions that add other functionality, including a project planner, mail and news reader, debugger interface, calendar, and more. Many of these extensions are distributed with GNU Emacs; others are available separately.
