I haven’t seen it yet, but I haven’t run it very many times.

We could try passing “universal_newlines=True” to the subprocess.Popen() constructor. This will open stdin/stdout/stderr in text mode, using the current locale setting. Python 3.6+ allows specifying the encoding in the constructor, if that makes a difference. Another option would be to manually wrap the output streams in an io.TextIOWrapper, which is essentially what Popen() does when given any of these arguments.
