The cast to `char*` here looks odd. The 'W' suffix in the function name 
indicates that it's the UTF-16 variant. It should be taking a `wchar*`, 
not of a `char*`. This might hint at a wrong declaration which could 
lead to memory corruption.

(The cast shouldn't be necessary anyway. `null` converts to all pointer 
types.)
