And that does not require PUA codepoints; moreover, your response does not
escape the fact I was pointing out that a standards body will not be
publishing standards that make reference to PUA codepoints.

And they won't be standardizing on symbols encoded using PUA codepoints.

Then you obviously don't understand the process.

The alternative to agreeing on a standard? None, but why would you need an

That is hardly the concern. Standards are designed to be international
agreements that foster international commerce; such IT standards are
intended to be international agreements on data representation or
processing protocols on which interoperable products can be developed. In
order to ensure reliable interoperation, they will not build standards on
anything that isn't standardized. PUA codepoint usage is not standardized,

Wrong. There is no consistency if company A decides to follow one set of
PUA character assignments while company B uses a different, incompatible
set. As long as PUA codepoints are used, that is going to be at stake.

I think I'm about to set up that "default-ignorable post" rule.

Your and our time would be much better spent if you were contributing to
getting the set of symbols finalized and getting proposal documents
prepared to have them added to ISO 10646 than by proposing PUA codepoints
to members of this list.

I'm suggesting that you take your PUA discussions elsewhere so that the
information value from the Unicode mail list can be maintained for the rest

Wouldn't you have a greater likelihood of reaching your target audience on
a forum dedicated to interactive television?

Think about the workflow for such magazines and then tell me again you're
not suggesting PUA codepoints for use in interchange.
