Okay. string->chars[0] is uint32_t so the above is identical but
the code looks bad in general?

len = oop_num_fields (stringOOP);
result = (wchar_t *) xmalloc (len + 1);


'12345678' asUnicodeString basicSize
=> 8

There is barely any C API using "wchar_t" so it is no surprise
the code might be broken. I think it needs to be:

result = (wchar_t *) xmalloc ((len + 1) * sizeof(*result)); 

and then maybe size(*result) == sizeof(string->chars[0])

I am flying right now but what is the GNU coding style? I have
my phases with !flag or flag == 0. I would only change it if there
is either a majority in our code or GNU coding style has a
statement about it.
