EmEditor Professional, a lightweight text editor for Windows, supports Unicode (UTF-16, UTF-8, and UTF-7), as well as many international encodings. EmEditor allows you to open huge files (248GB or larger) quickly and easily, and is optimized for speed and reliability. The Large File Controller maximizes productivity by opening sections of enormous files for faster editing.
In a speed comparison test, EmEditor performed better than 10 other text editors in four different categories, including launch time and time to open large files.
Features include JavaScript or VBScript macros, plug-ins, syntax highlighting (including embedded scripts in HTML, ASP, and PHP files), drag-and-drop, CSV and TSV mode, Narrowing, Brackets/Quotation Mark Auto-Complete, and much more. The text editor supports not only JavaScript and VBScript for the text editing macros, but also PerlScript, PHPScript, Python, Ruby, and many other ActiveScript languages as long as the script engines you want to use are installed on your system. Binary (ASCII View) and Binary (Hexadecimal View) are included in the available encodings.
The text editor can record and play keystrokes and mouse operation against other applications, and includes plug-ins such as Projects and Word Complete, lots of objects for macros, the Macros Toolbar, and portability options (such as USB drive setup), virtual space mode, wrap indent, smooth scroll, and crash auto-recovery.
