Where? I haven't seen one for many months, and they disappear rather
quickly these days ...

Netscape 3.0 for Unix has in the Options|Mail and News Preferences|Compose
menue a section
When composing Mail and News Messages
Send and Post: X Allow 8-bit _ MIME Compliant (Quoted Printable)
with the default on "Allow 8-bit". I would suggest, in case this switch
is set to allow 8-bit and the outgoing message contains any character

If the MIME Compliant option is selected, then if there are > U+00FF
characters in the message, then use UTF-8 in the quoted-printable encoding.
If there should be *really* a high demand for UTF-7 from the customer base,
then you can easily add a third menu item
_ MIME Compliant (UTF-7 for Unicode)
but I doubt that anyone will really care. UTF-8 is the recommended
default encoding for the future of the Internet, so lets worry about
alternatives only if it turns out that we *really* need it.
Using UTF-8 in quoted-printable or base64 encodings has the big advantage
over UTF-7, that modern ESMTP agents can automatically convert between
quoted printable and 8-bit, but they know nothing about UTF-7, and
this way, UTF-7 somehow falls out of the concept.
