RC6 is a block cipher. "×" is a common symbol for multiplication.

I've been doing multiplication for close to 50 years now, and I've
never seen that symbol used for it or anything else. Maybe it looks
different to you than to me - to me, it's diamond-shaped.

My earlier messages contain these MIME headers:

Mime-Version: 1.0
Content-Type: text/plain; charset=iso-8859-1
Content-Transfer-Encoding: 8bit

It's then up to your favourite proper newsreader to parse this and
conclude that the message body is 8-bit ISO-8859-1 and decode it.

Right -- put the burden on the multitude of others, why don't you?

I'm formatting my current message in UTF-8 on purpose. If your
client now shows the sign properly, it is MIME-challenged and should
be repaired or erased. After all, the MIME standard covering this has
already become ten years of age.

But the standard on usenet (or at least in sci.math) is _not_ to use
any special encodings. While it might look prettier to encode x
squared using a superscript, the standard is "x^2" which is
automatically compatible with every type of newsreader. Moreover, we
are all used to reading it in that form. You are not single-handedly
going to change the standard. To change it, there would have to be an
overwhelming consensus, not just an occasional post bucking the norm.

Since you were probably unaware of the sci.math conventions, your
ignorance is easily forgiven. However, when you were alerted to a
problem with reading your post, you should at least have looked back
over a sample of sci.math posts to see what the standard actually is,
before insisting that others adjust or replace their newsreaders to
conform to your preferred encoding.
