I can't speak for Code2000 and Junicode, but the use of PUA in Gentium is
guided solely by the needs of SIL and those with whom we have close working
relationships.

Fine. Please continue that discussion offline with the individuals
interested in those characters.

He doesn't need the help of this list as a whole. If he would like to get
help from individuals on this list, he can certainly ask for it. You, on
the other hand, are ever making it the business of this list to help people
with PUA usage, even when they haven't indicated desire for such help.

They do not, and cannot.

I am using the word "cannot".

If the question were only in relation to a specific selection of fonts, all
you would need to do is inspect those fonts; you don't need to ask the
list. And if the people interested in these characters care about those
fonts, then let them look, or talk to the developers of those fonts if they
feel the need.

It would be impossible to tell you of every private use of F200.F2FF. I can
tell you that SIL is using them for various Latin characters that are not
yet encoded in Unicode, but unless someone is engaged in interchange of
information with SIL authors or planning to do so, that's irrelevant. I had
planned on sending *a single notice* to this list once I had our current
assignments documented and published on the web, but your obsession with
others' PUA assignments is making me think twice. I have no intent of
making long-winded discussions involving SIL usage of the PUA one more
thing members of this list get subjected to against their wishes.
