FileTestW

Calls the Unicode (wide) versions of the Windows API’s file functions.

It’s a subclass of the standard FileTest class that only overrides the methods when it’s run on a Windows system. Otherwise it functions as a normal FileTest class. File methods not re-implemented will behave as normal - trying to call the ASCII Windows API.
