Re: CTE:

                                                      Some person
says that quoted-printable is the one.

        I think that was Patrik.   Perhaps others too.   Personally,
I avoid QP (quoted-printable) whenever possible.   It seems to be best
suited to files that are  "mostly text"  or  "mostly 7-bit clean".
If you want to send something like a GIF or an executable,  or even a
spreadsheet,  I would strongly recommend Base64 instead.

        QP does not survive as nicely as one might hope.
(could be my own peculiar thinking about linend and line definition)
If your biggest problem is that you want to retain,  say,  TAB characters
and the rest of the mailed item is just ordinary text,  then QP is fine.
For something like ISO-2022-JP,  where heavy use of ESCape is expected,
then QP is preferred.

This time I'd like to ask Europe environment. In ISO-8859-1 area, 8bit
data ISO-8859-1 is usually send directly before MIME? Or
quoted-printable encoding exists and pepole used to use it before
MIME?

        I'm not European,  so I bow to their statements about their own
experience.   Also,  I cannot speak about pre-MIME ISO-8859 uses in mail,
except to say that (even now)  I find many mail gateways stripping that
high bit.   8859 is a good candidate for QP if you have  "just a few"
characters with that high bit set.   Names like Andr\xE9 look right.   ;-)

  ...     I let 5 Japanese people read
draft-ietf-822ext-mime-imb-01.txt and ask, "What CTE: you think shoud
be used for ISO 2022 JP as long as you read this I-D?"
All people answered 8bit or Base64.

        Base64 is the safest.   It's also (obviously) the least
readable by non-MIME mail readers.   :-(

Can we say that a documents that includes control-l like RFC is
US-ASCII?

        I vote "yes".
