I think you have incorrectly assumed that Bonita is asserting that there
are no more than 65536 Unicode codepoints.
UTF-16 can represent all Unicode codepoints. It cannot represent each
Unicode codepoint in 16 bits; some of them require two 16-bit values.
I presume Bonita meant that UTF-16 can represent all of Unicode (which
is true). But a 16-bit wchar_t cannot, because the standard requires
wchar_t to be "able to represent all members of the execution
wide-character set" (that's the point Bonita missed or ignored).
To use wchar_t to represent all Unicode code points, you either have to
make wchar_t at least 21 bits (more likely 32 bits) *or* you have to use
it in a way that doesn't satisfy the requirements of the standard, such
as using UTF-16 to encode some characters in more than one wchar_t.
