Mined provides both extensive Unicode and CJK support offering many specific features and covering special cases that other editors are not aware of (like auto-detection features and automatic handling of terminal variations, or Han character information).
Mined supports full mouse control and menu system in plain-text terminals (and it was the first editor supporting Unicode in xterm).
Mined offers a full set of text and file management features, like data loss prevention ( using backup, recovery files, and file locking interoperable with other editors, and file change monitoring), an interactive file chooser, and an interactive file switcher.
Basically, mined is an editor tailored to reliable and efficient editing of plain text documents and programs, with comfortable features and intuitive interactive behaviour designed for this purpose.
