No. On several platforms (at least windows, 32-bit AIX, and 32-bit
z/OS) wchar_t is only 16 bits. We therefore cannot rely on wchar_t
being sufficiently large for use as a scalar value. This, plus the fact
that the character encoding used for wide literals varies across
platforms makes wide character functionality non-portable. I consider
the existing POSIX wide character support a dead end.
