The later. But if wchar_t is 16 bits, it can only encode Unicode 3.0 or
before. ie no UTF-16 support.

Surely if wchar_t is 16 bits, it CAN be used to encode the whole of
Unicode with UTF-16, i.e. with supplementary plane characters
represented as "surrogate pairs" in pairs of wchar_t. Whether these
characters SHOULD be represented as UTF-16 code units in a wchar_t
string (or whether representation should be either UCS-2 or UTF-32) is a
separate issue, probably related to how the associated libraries handle
the code units for surrogates.
