Doug, I don't know who you are accusing of failing to see this
distinction, but it certainly isn't me. I have made it very clear
several times that I understand that IN PRINCIPLE I am free to write my
own operating system, or a large part of it, to display these characters
as I wish. The problem is one IN PRACTICE.
Your advice reminds me of the advice that might have been given to
Burbage (?) not to hire Shakespeare, but rather to use a team of monkeys
because given enough time they would write the same plays - true, but
not practical. The ones I am comparing to monkeys are would-be PUA users
like myself who are no more capable than monkeys of writing OSs in a
sensible time frame. (Sadly there are no OSs in the Shakespeare
But this practical problem would go away (in time, but a lot less time
than it would take me to write an OS!) if Unicode specified different
DEFAULT (read "only ones supported in any commercial or open source
software") properties for parts of the PUA, and the software companies
implemented this - which would be trivial if specified.
You claim to have customised the properties of PUA characters. Do you
mean that you have written software which processes them according to
your customisations? It is easy to list properties. It is very hard to
implement them, if one has to start from scratch, without any help from
the established manufacturers.
