Aside: D has syntax for "// For wchar_t.": `import core.stdc.stddef:
wchar_t;`.

wchar_t is not wchar. wstring is not (portably) compatible with a
wchar_t array.
If you actually have a wchar_t* and you want a wstring as opposed to a
wchar_t[], then you will potentially have to do some converting.
If you have a wchar*, then don't use wcslen, as that's defined in terms
of wchar_t. There may be some function for finding the first null wchar
from a wchar*, but I don't know it, and writing out a loop isn't exactly
hard:
----
wstring toWstring(const(wchar)* value)
{
if (value is null) return null;
auto cursor = value;
while (*cursor != 0) ++cursor;
return value[0 .. cursor - value].dup;
}
