Thanks for your comment,

I've read RFC1652 and recognized most of SMTP server today has already
have 8BITMIME body option (ESMTP).

Evenif the RFC is made, it will need time to spread into implementations.

Talking about PC(Windows PC), the latest versions of Microsoft Outlook
Express and Outlook 2000 support UTF-8. Some of 3rd party mail softwares
also support UTF-8 in the latest beta version, although the connectivity/
interoperability is not fully tested yet. 
On the other hand, most of PDAs(HandHeldPC, PalmPC, CellerPhone with
Internet access capabilities) are not ready for Unicode/UTF-8, and there
is low market pressure. Most of Japanese consumers even don't know what
UTF-8 is.

I don't like UTF-7, neither, It is too complex.

Although I'm not enthsiastic to the Unicode/UTF-8, I believe one solution
is better than three solutions (iso-2022-jp, Shift-JIS and EUC, all of
them are used in current Japanese environment). However, it is the truth
that not the all Japanese-enabled Internet equipments are not ready for
Unicode/UTF-8 today. The transition is going slowly, perhaps will take
years to complete. I don't know very much about other Asian countries,
but I belive the situation is similer to my country.

I think UTF-8 and 8BITMIME should be defined as MANDETORY for IPP mail
notification, and the compatibility methods(i.e iso-2022-jp and base64)
should be defined as OPTIONAL.
