Windows 8 UTF-8 decoding problem

What steps will reproduce the problem?
1. install python 3.4 and psutil 2.0.0 on Windows 8
2. create system_infos.py file with the following line:
   import psutil
   net_info=psutil.network_io_counters(pernic=True)
   print(str(net_info))

3. python system_infos.py

What is the expected output?
{'lo': snetio(bytes_sent=112432, bytes_recv=112432, packets_sent=804, 
packets_recv=804, errin=0, errout=0, dropin=0, dropout=0), 'wlan0': 
snetio(bytes_sent=0, bytes_recv=0, packets_sent=0, packets_recv=0, errin=0, 
errout=0, dropin=0, dropout=0), 'eth1': snetio(bytes_sent=1228441, 
bytes_recv=17944089, packets_sent=7654, packets_recv=24378, errin=0, errout=0, 
dropin=0, dropout=0), 'eth0': snetio(bytes_sent=0, bytes_recv=0, 
packets_sent=0, packets_recv=0, errin=0, errout=0, dropin=0, dropout=0)}

What do you see instead?
