CTE:

Thanks to many discussions on this list, I understand the design
intention of charset. MIME allows to include ISO 2022 JP if charset
label is specified.

This time I'd like to ask about a CTE: issue. When I send a letter
whose body-part is "CT: text/plain; charset=iso-2022-jp", which CTE:
should I use? How about ISO-8859-1?
