Unicode support

EmEditor supports Unicode and provides tools for work with various character encodings. These features include automatic encoding detection, byte order mark support, file reload with a different encoding, and detection of encoding errors. EmEditor can use any encoding supported by Windows and easily converts from one encoding to another. The program opens Unicode file names and searches for Unicode characters.

Large files

EmEditor is capable of working with very large files.[3] For large files up to 248 GB, rather than opening them in memory, EmEditor "spills them out" into disk space. For files over 248 GB, it uses its Large File Controller to edit separate sections of the file.


EmEditor is extensible via plug-ins written in C/C++. The editor's API is available, so that users can write their own plug-ins.

The following plug-ins are installed with EmEditor by default:

  • HTMLBar
  • Open Documents
  • Outline
  • Projects
  • Search
  • Snippets
  • WebPreview
  • WordComplete
  • Word Count

An optional 32-bit plug-in for CSE HTML Validator support is also available.[4]

Scripting macros

The program is scriptable using the Windows Script Host. The program's scripts are written in either JScript or VBScript. EmEditor can generally be scripted in any scripting language that supports Active Scripting. The program includes powerful macros.[5]
