As soon as you leave the UTF-16 base plane, you need to deal with
surrogate character pairs.  The issues are pretty much the same as
when dealing with UTF-8, and you get the additional complications of
wide characters, quite more conspicuous byte order marks, Endianness
portability problems and so on.

In short: this buys you positively nothing unless you restrict
yourself to the base 16-bit subset (which makes this infeasible for a
number of tasks).  And even then, the disadvantages are not really in
a good balance with the advantages.
