気がつくと文字化けしていた。 (require 'un-define) (coding-system-put 'utf-8 'category 'utf-8) (set-language-info "Japanese" 'coding-priority (cons 'utf-8 (get-language-info "Japanese" 'coding-priority))) (set-language-environment "Japanese") (set-terminal-coding-system 'utf-8) (set-keyboard-coding-system 'utf-8) (set-buffer-file-coding-system 'utf-8) (setq default-buffer-file-coding-system 'utf-8) これで直るらしい。
