Windows has full support for unicode, since it's an OS based on
unicode. It's old C code, which is not unicode-ready, and it
remains not unicode-ready without changing behavior. Modern code
like phobos usually tries to be unicode-ready.

Not s, but its address should be assigned to v:

Here, the pointer to the stack escapes the function. Don't do

Hopefully the D type system will be improved with scoping
tracking management, to turn similar operations into
compilation errors (as in Rust, but perhaps in a less refined
