(and in another posting quotes the C++ standard)

Like you say, the C and C++ standards require wchar_t to be large
enough so one wchar_t object can hold distinct values for every
character in the largest supported character set.

Most widely used operating systems today (eg, Microsoft Windows,
Linux) support character sets with (at least) hundreds of
thousands of characters.

Can you explain how hundreds of thousands distinct values can be
represented in a single 16-bit wide wchar_t object?
