R. International Character Set Support

Emacs supports a wide variety of international character sets, including European variants of the Latin alphabet, as well as Chinese, Cyrillic, Devanagari (Hindi and Marathi), Ethiopic, Greek, Hebrew, IPA, Japanese, Korean, Lao, Thai, Tibetan, and Vietnamese scripts. These features have been merged from the modified version of Emacs known as MULE (for "MULti-lingual Enhancement to GNU Emacs")

Emacs also supports various encodings of these characters used by other internationalized software, such as word processors and mailers.

Emacs allows editing text with international characters by supporting all the related activities:

You can visit files with non-ASCII characters, save non-ASCII text, and pass non-ASCII text between Emacs and programs it invokes (such as compilers, spell-checkers, and mailers). Setting your language environment (@pxref{Language Environments}) takes care of setting up the coding systems and other options for a specific language or culture. Alternatively, you can specify how Emacs should encode or decode text for each command; see @ref{Specify Coding}.
You can display non-ASCII characters encoded by the various scripts. This works by using appropriate fonts on X and similar graphics displays (@pxref{Defining Fontsets}), and by sending special codes to text-only displays (@pxref{Specify Coding}). If some characters are displayed incorrectly, refer to @ref{Undisplayable Characters}, which describes possible problems and explains how to solve them.
You can insert non-ASCII characters or search for them. To do that, you can specify an input method (@pxref{Select Input Method}) suitable for your language, or use the default input method set up when you set your language environment. (Emacs input methods are part of the Leim package, which must be installed for you to be able to use them.) If your keyboard can produce non-ASCII characters, you can select an appropriate keyboard coding system (@pxref{Specify Coding}), and Emacs will accept those characters. Latin-1 characters can also be input by using the C-x 8 prefix, see C-x 8. On X Window systems, your locale should be set to an appropriate value to make sure Emacs interprets keyboard input correctly, see @ref{Language Environments, locales}.
