On Windows, the application always receives command line arguments as 
wchar_t.  If you provide the narrow main() entrypoint method then it is 
the application's runtime startup code that will convert args back to 
ANSI using the ACP, not the console code page.  As such, interpreting 
argv as ACP is correct (albeit lossy if there were any Unicode 
characters involved -- the only truly correct design is to only use the 
wide entrypoint or ignore the entrypoint args and reparse from the 
original Unicode string).

Also on Windows, in most cases the console code page is also the ACP, 
although that is less true in more recent versions.
