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.
