Beware: there is no guarantee that the C wchar_t coding is the Unicode
codepoint (which is the same as UTF-32). You could decree that any system
where it is not true is just braindead, and I would agree. But that makes
Solaris¹, for example, braindead, and stopping to support it would require
at least some thought; Solaris has a reasonably working iconv, though.


1: in UTF-8 locales, the wchar_t value corresponding to an Unicode character
is indeed its codepoint, but in legacy 8-bit locales, the wchar_t value for
the character with code c >= 0x80 is 0x30000000 | (c & 0x7F). Which means
that the very same character has different wchar_t values in different
locales.
