I wish to call the CallWindowProc function. MSDN says this:
Windows NT/2000: The CallWindowProc function handles Unicode-to-ANSI conversion. You cannot take advantage of this conversion if you call the window procedure directly.

As I am calling this from a system-wide hook for a window I didn't create. How do I determine if this window should use the unicode version? Does it matter if I call the wrong one?
