Use subprocess.run with encoding="utf-8"

	try:
	result = subprocess.check_output(subprocess_args, stderr=subprocess.STDOUT)
	except subprocess.CalledProcessError as e:
	return e.output.decode("utf-8"), e.returncode
	return result.decode("utf-8"), 0

if you pass encoding='utf-8' to subprocess.run, your strings are automatically decoded:

>>> s = subprocess.run("/bin/echo 'hello'".split(" "), stdout=subprocess.PIPE)
>>> s.stdout
b"'hello'\n"
>>> s = subprocess.run("/bin/echo 'hello'".split(" "), stdout=subprocess.PIPE, encoding="utf-8")
>>> s.stdout
"'hello'\n"

So:

    try:
        result = subprocess.check_output(subprocess_args, stderr=subprocess.STDOUT, encoding="utf-8")
    except subprocess.CalledProcessError as e:
        return e.output, e.returncode
    return result, 0
