RFC 1428, page 3.

   A site may "upgrade" to MIME en-masse by implementing MIME conversion
   for all messages leaving the site.  For text messages, the body can
   be converted by adding a MIME-version header and a Content-Type:
   Text/Plain with the character set in use in the site, provided the
   site uses a single character set.

   An appropriate Content-Transfer-Encoding header line must be added to
   indicate any encoding that may be necessary.

       MIME-Version: 1.0
       Content-Type: Text/Plain; Charset = ISO-8859-1
       Content-Transfer-Encoding: 8bit

   If no information about the character set in use is available, the
   gateway should upgrade the content by using the character set
   "unknown-8bit". The unknown-8bit value of the charset parameter
   indicates only that no reliable information about the character
   set(s) used in the message was available.
..................and on page 5:
   The interpretation of the "unknown-8bit" is up to the mail reader.
   It is assumed that in many cases the human user will be able to
   interpret the information and choose an appropriate character set or

It is not widely used, as far as I know; any sane person would avoid it if he 
could. So should we!
