Mingw64 was being difficult, so instead of defining a wmain entrypoint, the command line parameters are parsed manually using built-in Windows methods that support Unicode. The results are converted to UTF8 and handled just like the rest of the linux/mac version of the code. This also removes dependencies on std::istream in favour of a FileInputStream which calls the appropriate unicode version of open to read a file. No speed regressions found on Linux or MacOS.
