'wwchar_t' means "wide wide character".

In fact it's not really an "extended" character or "complex character".
It's just what POSIX calls a 'wchar_t'.

I like the analogy between strtol and strtoll. In the beginning, people
thought a 'long int' would be enough for everything. Then they discovered
a 'long long int' is needed. The same story repeats itself here with
the "wide characters" which turn out to be not wide enough, and
"wide wide characters" are needed.

Indeed this meaning can come to mind, but I think it's not dangerous
since the term "world wide" has no meaning in a programming language.
