That’s not entirely accurate: using the CreateProcessW API, you could
pass UTF-16. However, in order to make full use of arguments passed
that way, the sub-program needs to forgo the normal “int main(int,
char**)” signature and use “int _wmain(int, wchar_t**)”, or to call
GetCommandLineW and parse the returned UTF-16 string. A sub-program
that accepts arguments via the usual ‘main’ function will be limited
to characters that are representable in the current codepage.
I do not know whether MSYS binaries do that.
