Yes. I don't like open() guessing the enconding:

   The default encoding is platform dependent (whatever
   locale.getpreferredencoding() returns)

Also, I don't like sys.std* guessing the encoding:

   Under other platforms, the locale encoding is used (see

In each case, it would have been better to default to bytes just like
subprocess does.
