Of course, looking back at the job I did of explaining it here, it's
no wonder there has been confusion. The original subject was the support of
Unicode in computer code. By using UTF-32, or more accurately, the 32 bit
datatype needed to represent it, the code would be future-proofed against
expansions to the Unicode character set (which I believe would continue to
be represented in the corresponding updated UTF-32 spec as a flat mapping),
which has been generally acknowledged will happen only when we meet space
aliens with a really large alphabet. There is a lot of code floating about
right now that needs maintenance because it was not future-proofed only a
few years ago. My comment about the "4,293,853,186 character alphabet" was
a simple reminder that there are never any guarantees - that even
future-proofed software can find a future for which it is unprepared, but
that the risk of such hapenning can be made ridiculously small.
Do I make sense yet?
