in order to get proper unicode handling, one should ask win api
directly for cmdline:
myGetArgs = do
alloca $ \p_argc -> do
p_argv_w <- commandLineToArgvW getCommandLineW p_argc
argc <- peek p_argc
argv_w <- peekArray (i argc) p_argv_w
mapM peekTString argv_w >>== tail
foreign import stdcall unsafe "windows.h GetCommandLineW"
getCommandLineW :: LPTSTR
foreign import stdcall unsafe "windows.h CommandLineToArgvW"
commandLineToArgvW :: LPCWSTR -> Ptr CInt -> IO (Ptr LPWSTR)
