I hope you realize that this is just a quick hack, which cannot work
in general, yes? For starters, the command line is not a file name,
in general, so using filename_to_utf16 is inappropriate. Also, I
think the environment variables need to be converted to UTF-16.

What exactly did you run from cmd.exe? What command?

Windows tries to interpret UTF-8 as something else?
