Hi all,
I am planning some win32 hobby projects. Now I have this function to tackle the LPCWSTR data type in win32.

private import std.utf;
auto toWString(S)(S s) { return toUTFz!(const(wchar)*)(s); }

Is there any better way to do this ?

iirc that's toUTF16z

You may try using tempCStringW from std.internal.cstring. It uses small string optimization. However the api is internal, so I'm not sure how valid it is to use this function. The returned struct is a temporary buffer so you must ensure that you don't escape dangling pointers.
