Actually you don't need to re-write Windows, Mac OS, etc., you "only"
need to hook into the text management and rendering engine of your OS and
re-write that subsection of the code. But, of course, you do need to know
what you're doing here and it isn't that easy, or cheap. (It could take
months, and thousands of dollars.)
At some point it can indeed become unrealistic, snobbish, self-serving,
and even lazy to just casually toss out the "do-it-yourself" crumb. There
is a lot to be said for a high level of text management and rendering
support resulting from the contract between operating systems and
standard encodings - otherwise everybody would be going their own way. As
is usual in such engineering and marketing situations, one must weigh the
trade-offs carefully. If there is a reasonable way to support what end
users want, or need, to do, then it should be taken seriously.
Unfortunately, and not uncommonly, inertia dominates. At some level, in
the absence of sufficient external force, we are all resistant to change.
I'm not really taking sides here on this PARTICULAR issue, I just wanted
to point out that we are all aware that we can do our own thing; but this
should really be the tactic (and advice) of last resort.
Currently, I view the PUA as practically a wasteland, unusable for even
for the most basic research work. On my OS of choice, I can't even encode
a font for the PUA user area and expect simple left-to-right display of
my glyphs, much less right-to-left. Yes, I can hook the OS and do this on
my own, but the question remains why should I, and why should EVERYBODY
ELSE, have to do this when some such minimal support could be built into
operating systems conformant to Unicode standards? (And this is not
really rocket science either.)
Is it simply out of the question, to review PUA policies and
implementation in Unicode? Could not the PUA, or possibly multiple PUA's,
retain their almost wild west independence and entrepreneurial spirit,
and still have a few sheriffs hanging around here and there to impose
some minimal expectation of law and order?
