After getting in this morning from the three day holiday (which I took
from my machine as well) and noticed the barrage of posts relating to
the "all over the net" quote I have to sheepishly admit that I was
(unintentionally) exaggerating--bad choice of words. The Unicode samples
I've taken come from two mailing lists and three newsgroups... one from
Handai (Osaka Univ's I18N Soft Eng project), a private ML from Kubota
systems, and newsgroups internal to Omron systems. Furthermore, all the
cases of "UNICODE-1-1-UTF-8" are due to the same alphaware EMAC mail
extension... apparently a bug.
The language I should have used was "all over -my- net." Apologies for

Um, many Japanese ISPs using sendmail still intentionally strip the 8-th
bit in e-mail to force their users to conform to standards (there are
many so-called Japanese e-mail programs that will allow one to send and
receive Shift-JIS and EUC-JP, which causes great grief for ISPs when
they have to explain to customers why their Japanese e-mail gets sent
correctly to x & y but not z). By stripping the 8-th bit, it forces
their customers to use ISO-2022-JP, which guarantees that all Japanese
e-mail/news software will be able to use it. If all so-called Japanese
software worked properly, this wouldn't be a problem, and ISPs wouldn't
have to "censor" the eighth bit. But most don't do this.

Says who? Popular rule? I am fully aware of the drawbacks of UTF-7 (and
the benefits), but I have yet to see any word about UTF-7 being
