Keld,
the required support for ISO-8859-* is stated in RFC 1521 as:

      Text:

            -- Recognize and display "text" mail
                 with the character set "US-ASCII."

            -- Recognize other character sets at
                 least to the extent of being able
                 to inform the user about what
                 character set the message uses.

            -- Recognize the "ISO-8859-*" character
                 sets to the extent of being able to
                 display those characters that are
                 common to ISO-8859-* and US-ASCII,
                 namely all characters represented
                 by octet values 0-127.
