UTF-16 works fine, but is a poor solution in almost every case.  As I 
said previously, it combines the disadvantages of UTF-8 with the 
disadvantages of UTF-32, giving the benefits of neither.  People know 
this - that is why it is not used in any significance except in places 
where it is hard to avoid (Windows programming), or for dealing with 
legacy code.

There was a time, long ago, when Unicode was young, when 16-bit was 
enough for almost everything, when saving a few bytes was important, 
when HTML and XML were not common, and when transparent compression was 
rare.  In those days, UTF-16 made sense for some uses.

Given a free choice without worrying about compatibility with old code 
or interfaces, no one would recommend or choose UTF-16 now.

No one has doubted that UTF-16 is a valid Unicode encoding.  That has 
never been in question.

As seems to happen so often, you have totally misunderstood the issue 
when you have been shown wrong.  I wonder if it is intentional.
