Judging from the code below, this would mean that the iterator
implicitly specifies the internal string type? Something like
typename iterator_traits<I>::container_type cont;

You can't assume wchar_t is UTF-32. You can't even assume it's 32 bits.

You can't assume short is 16-bits (but that's more or less academic).
