In Japan, ISO-2022-JP (so-called JIS encoding) is a de facto standard,
and still commonly used for e-mail. ISO-2022-JP is a 7-bit encoding
with escape sequences, so it used to be useful for MTA/MDA which don't
accept 8-bit stream. The default Japanese encoding of Sylpheed is
ISO-2022-JP (when using ja_JP.* locale).

Now, most of modern systems accept UTF-8, so it may be safe to use it in
many cases. Please note that some of Japanese still insist on using
ISO-2022-JP (especially on mailing lists which don't handle UTF-8 well).
