select-message-coding-system might not be the answer for all
situations, especially when a message contains characters in the
charset other than the default one.

Anyway, the solution for KOI8-R encoding is

 (if (fboundp 'put-charset-property)
    (put-charset-property 'cyrillic-iso8859-5
                          'preferred-coding-system 'koi8-r))
