`ws.length` is the length in `wchar`s, but `memcpy` expects
the size in bytes. (This is because it takes `void*` pointers
as inputs, and so does not know the element type or its size.)
How do I get this size in bytes from wstring?
`ws.length * wchar.sizeof` should do it. `wstring` is just an
alias for `immutable(wchar[])`, and the `length` property is the
number of `wchar` elements in the slice.
