    Thanks for your comment,

    >Not always. See RFC 1652. This extension is widely deployed and heavily

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

    >something similar to RFC 1652 for headers. However, waiting for the IDN

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

    >I believe this is an accurate assessment of the majority of use today. However,

    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.

    >And isn't likely to gain in popularity in the future. UTF-7 is a bad idea;
    >UTF-8 should be used instead.
    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.
