UnicodeDecodeError when running demo code

[dov]

Trying to run the demo code:

import os.path as op

from adb import adb_commands
from adb import sign_m2crypto

# KitKat+ devices require authentication
signer = sign_m2crypto.M2CryptoSigner(
    op.expanduser('~/.android/adbkey'))
# Connect to the device
device = adb_commands.AdbCommands.ConnectDevice(
    rsa_keys=[signer])
# Now we can use Shell, Pull, Push, etc!
for i in xrange(10):
  print device.Shell('echo %d' % i)

Fails as follows:

$ env PYTHONPATH=/space/pub-repos/python-adb:$PYTHONPATH python adb-demo.py
Traceback (most recent call last):

I'm using the latest git commit.

$ git log --oneline -1

I have the same problem

[geckogecko]

+1 I got the same error

[gauravkatoch007]

+1, I got the same error.
I also tried converting -
https://github.com/google/python-adb/blob/master/adb/adb_protocol.py#L190

total = sum(map(ord, data.decode('ascii')))
to
total = sum(map(ord, data.decode('utf-8')))

But still faced the same issue. I tried re-generating my adb keys as well, didn't help.
Works fine with adb in shell.
