Hans, perhaps you can tell me exactly where else you will find 8 x 256
16-bit code points which are not already allocated either as Unicode
characters or for the existing surrogate mechanism. According to the
Roadmap to the BMP, http://www.unicode.org/roadmaps/bmp/, the largest
currently unallocated area is just 80 code points. I trust it is obvious
to you why 16-bit code points are required.

There is in fact no problem at all! Except that 8 x 256 code points had
to be reserved, but there are plenty of code points.

All I am saying is that there is no problem with UTF-16, no need to
replace it, no desire for a change (as you note yourself), and no chance
that there will be a change - as long as there is a need for a 16-bit
encoding, which may not be for ever.
In theory of course there are plenty of alternative 16-bit encodings.
You can play around with them as much as you like, and even use them in
communication with your friends. But making any change without the
agreement of the UTC is even more pointless than getting them to agree,
as it fails to achieve the only slight advantage which would be gained
by the change, the availability of 8 x 256 more code points.
