- Supports a Wide Array of Document Types
- Jedit X can read Plain Text, Rich Text Format (RTF), Rich Text Format Directory (RTFD), MS Word, OpenDocument, Jedit 4, and SimpleText documents. It can also write Plain Text, RTF, RTFD, MS Word and OpenDocument documents.
- Unicode-Based Multi-language Support
- Jedit X is based on Unicode, which allows the same document to contain multiple character sets, including right-to-left languages like Arabic. This also provides an excellent environment for editing Unicode based documents such as XML or XHTML.
- OpenType Hiragino Support, with Over 20,000 Characters
- Jedit X supports the Hiragino typeface and its 20,000 characters contained in JIS X0213 (JIS 3&4).
- Sleek Aqua Interface
- Jedit X makes full use of Mac OS X’s Aqua for a simple, elegant user interface, such as sheets, drawers, customizable toolbars, etc.
- Plays Well with Other Cocoa Applications
- Jedit X is highly interactive with other Cocoa programs. For example, pasting from Safari to Jedit X carries over formatting, image and even link information.
- Utilizes Cocoa’s NSTextView Text Engine
- Jedit X makes use of Cocoa’s built-in NSTextView text engine, which provides high-performance text-editing features like back tabs, center tabs, kerning, ligature, superscript, and subscript. Jedit X also offers its own capabilities, including line numbering, invisible character display, custom word wrapping, split windows, and more.
Improved Search and Replace
Search and replace has been made even more powerful and easy to use in Jedit X. New capabilities include faster Replace All, a handy search and replace history, internal processing of batch search and replace operations (up to thousands at a time), and search and replace from the Toolbar.

- Powerful Regular Expression Handling
Jedit X uses OniGuruma, the regular expression engine used in the object-oriented language Ruby. This powerful and flexible regular expression engine far surpasses the engine used in
Jedit4.0.
