UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 10: ordinal not in range(128)

Long story short, one of my relatives got a Neato rob and I quickly searched the web to see if it was remotely usable. I found your repo and since I'm currently experimenting with PyQt4, I decided to write a very basic UI for controlling the robot.

• Installed with pip
• python --version : Python 2.7.15rc1
• Works without hiccups with the interpreter

However, things go wrong when I try to initialize the robot.

PyQt code (important bits)

from PyQt4 import QtCore, QtGui
from pybotvac import Robot

try:
    _fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
    def _fromUtf8(s):
        return s

try:
    _encoding = QtGui.QApplication.UnicodeUTF8
    def _translate(context, text, disambig):
        return QtGui.QApplication.translate(context, text, disambig, _encoding)
except AttributeError:
    def _translate(context, text, disambig):
        return QtGui.QApplication.translate(context, text, disambig)

        robot = Robot('[REDACTED]','[REDACTED]',u'maps','[REDACTED]')
        def __start(self):
            robot.start_cleaning()

        def __stop(self):
            robot.stop_cleaning()

        def __return(self):
            robot.send_to_base()

        self.startButton.clicked.connect(__start)
        self.stopButton.clicked.connect(__stop)
        self.returnButton.clicked.connect(__return)

Temporary fix

I found this answer on StackOverflow, but I feel it is bad practice and kind of hackish.

I already found a quick dirty workaround for executing the robot's command : separating each of them in single file and call them in a subprocess, like this :

from subprocess import call as run
[
.
.
.
]
def __start(self):
  run(["python","startCleaning.py"])

But I think it's not very convenient.
