That problem of Unicode is technical, not political.

Just as characters in Greek and English are different, characters in
Japanese and Chinese are different and should be assigned different
code points, if we need to use Unicode without furthur specification.

Instead, if you must support the both specification:

	unicode-japanese

and

	unicode-chinese

it is not so useful because you can't assume a single default. If we
can allow for further profiling information, there is no reason not to
allow all the registered charsets of MIME.

> Has that been settled?

It depends.

It seems to me, now, that many people who contributed to Unicode thinks
Unicode should be used with further profiling information such as

	unicode-with-ascii-characters-only

	unicode-with-english-and-french-characters-only

and then, 

	unicode-japanese

	unicode-chinese

will also be naturally supported.

But then, I can, by no means, say Unicode "Universal".

Again, if we can allow for further profiling information, there is no reason
not to allow all the registered charsets of MIME.

Thus, IMHO, the issue is settled in a sense which makes the adaption of
*THE SINGLE* character set: Unicode quite inappropriate.

Unless you think WNILS needs its own further discussion on character
encoding, please direct the discussion to other mailing lists or
directly to me (Reply-To is set so).

PS

It should be noted that whois service in Japan by JPNIC is using
ISO-2022-JP encoding of RFC1468.
