I don't think so.  There's no reason why you shouldn't define a
language environment corresponding to ja_JP.UTF-8 which turned it on
(not that language environments is the right approach to locale
handling).

Anyway, there seems to be very little interest from users; I don't
recall any of the contributions I expected.  Mostly I've just had
unhelpful remarks from non-CJK users.

Yes.  If I remember correctly, I posted measurements.

It doesn't make sense to dump it, the way it works.

As far as I remember, that's why I didn't implement that sort of
thing.  post-read-conversion machinery is already there, I think.

[Is this code base ever going to be released so that most users
actually can use it?]
