Want to get UTF-8 (unicode) to work on Emacs but don't know where to start?
Snarf this, and toss it in your .emacs.
;;;;;;;;;;;;;;;;;;;;
;; set up unicode
(prefer-coding-system 'utf-8)
(set-default-coding-systems 'utf-8)
(set-terminal-coding-system 'utf-8)
(set-keyboard-coding-system 'utf-8)
;; This from a japanese individual. I hope it works.
(setq default-buffer-file-coding-system 'utf-8)
;; From Emacs wiki
(setq x-select-request-type '(UTF8_STRING COMPOUND_TEXT TEXT STRING))
;; MS Windows clipboard is UTF-16LE
(set-clipboard-coding-system 'utf-16le-dos)
The part about the clipboard-coding-system is essential for MS windows users who want to transfer content back and forth between windows apps and Emacs.
