You can use argv for path arguments, but only if you're using wmain or 
wWinMain entry points and using the wchar overloads of Filesystem.

main or WinMain entry points receive ANSI-codepage arguments, which are 
guaranteed to not be UTF-8 and are never safe to use as filesystem paths.

argv[0] is broken everywhere; it can be set fairly arbitrarily by 
whoever launches the process, on all platforms.
