  There are a fewer software that supports ISO-2022-JP-2 for various
reasons, but it is still a member of ISO-2022 family, which a
reasonable emailer should support.  And, because vast majority of
(pretty much "virtually all") email traffic in Japan use ISO-2022-JP
(which is the standard anyway); so I'd send emails with some Japanese
characters in ISO-2022-JP.  Anybody who wants to communicate in email
in Japanese should use an emailer that supports ISO-2022-JP.  And
anybody who wants to talk about the glyph differences in Japanese and
Korean (if "plain text" is preferred) would get better results with an
emailer that supports ISO-2022-JP-2.

  It doesn't have to be separated entry for ISO-2022-JP and
ISO-2022-JP-2.  If you save my email as it is to a file, open the file
with Firefox by specifying file://... and change the encoding to
ISO-2022-JP, Firefox certainly display it correctly.

  Hmm.  JIS X 0208 was the national standard and predates Unicode.

  "Deja-Vu" is French; the answer to the original question is no and
Blaming Microsoft doesn't help there.
