"Outer world" encoding for non-Latin1 language environments

[Anton Zinoviev]

Hi!

Even when users choose some non-Latin1 language environment Emacs
doesn't suppose that it's new default encoding is actually the
encoding of the X-clipboard, the console font, etc.  This can be
easily changed in this way:

(set-language-info-alist
 "Ukrainian" `((documentation . "\
Support for Ukrainian with KOI8-U coding system.  If you prefer
UTF-8, please put in ~/.emacs the following line:
  (prefer-coding-system 'utf-8)")
                (charset ascii cyrillic-iso8859-5 mule-unicode-0100-24ff)
                (sample-text . "here some Ukrainian tekst")
                (setup-function . setup-koi8u-coding-system)
                (exit-function . reset-coding-system)
                (coding-system . (koi8-u utf-8))
                (coding-priority . (koi8-u utf-8))
                (nonascii-translation
                 . ,(get 'cyrillic-koi8u-nonascii-translation-table
                         'translation-table))
                (input-method . "cyrillic-ukrainian")
                (unibyte-display . cyrillic-koi8u)
                (features cyril-util))
 '("Cyrillic"))

Note the (setup-function . setup-koi8u-coding-system) and
(exit-function . reset-coding-system).  They can be defined by
(features cyril-util) in this way:

(defun setup-koi8u-coding-system () 
  (let ()
    (set-keyboard-coding-system 'koi8-u)
    (set-clipboard-coding-system 'koi8-u)
    (set-terminal-coding-system 'koi8-u)))

(defun reset-coding-system () 
  (let ()
    (set-keyboard-coding-system 'latin-1)
    (set-clipboard-coding-system nil)
    (set-terminal-coding-system nil)))

Maybe someone will propose a better solution?
