Re: [tlug] Japanese Encoding - which one?

[Evan Monroig <evan@example.com>]

Thanks for answering ^^.

As you say, email must be sent in 7bit text, and when it is 8 bit it
must be encoded to Base64 or Quoted-Printable for transport.

In all case you will need MIME headers, and after reading RFC1468
whose link you sent us, I understood that ISO-2022-JP is 7bit by
nature, so there is no need to encode it before transport. By the way,
the RFC described only what is ISO-2022-JP, not if we should/must use
it or not...

Now when we say that ISO-2022-JP is better for Japanese, what it means
(I guess) is that some devices/software cannot understand anything
else... But because of that, we can't communicate using those
devices/software in other languages... In my emails I like to mix
French and Japanese, and there is no way that I can do that with my
cellphone or with (French-speaking !) japanese users of hotmail...

(and with French I am quite lucky most letters are ASCII.)
