CJK is a macro package for LaTeX, providing simultaneous
support for various Asian scripts in many encodings (including
Unicode): Chinese (both traditional and simplified), Japanese,
Korean and Thai. A special add-on feature is an interface to
the Emacs editor (cjk-enc.el) which gives simultaneous,
easy-to-use support to a bunch of other scripts in addition to
the above -- Cyrillic, Greek, Latin-based scripts, Russian and
Vietnamese are supported.
