I don't think the standard says that? Isn't this only because
the current set is small enough to fit? So this may change as
Unicode grows?
No. Unicode uses only 21 bits and it is very unlikely to change
anytime soon as barely 17 are really used. This means the current
range can be grown by more than 16 times what it is now. So
definitely, one UTF-32 codeunit is guaranted to hold any
codepoint, forever.
