Sorry, I just can’t resist pointing out that difference between
hardware and software is only the fact that the former is material,
with all the consequences that follows. In any other way they are
completely interchangeable.

As for the other part of your mail, Peter, sorry, but it really
doesn’t make any sense to me. As John has pointed out, you can adjust
the properties of private use characters on Apple computers. Perhaps
there is a way to do so on Windows, Unix and other systems as well.
What Philippe and Doug are proposing, and I also strongly agree with,
is to have a standard way of interchange of these properties. I don’t
think it is neccessary to go into the advantages of standards.

Speaking of actual implementation, I’m convinced that this format
should be the same as it is for encoded characters (whether it is the
plain text format of the Unicode Character Database, XML or anything
else). Rendering engines should – maybe they already do so – accept
multiple files containing character properties, which could make
upgrades to the newer versions of the standard a matter of downloading
the new standard set, and provide a way of overriding private use (or
even standard if one is so inclined) characters’ properties.
Introduction of unencoded scripts would therefore become a matter of
distributing a small properties file and the corresponding fonts.
