psutil.net_io_counters() return same value every time on some machines

[EvinceMoi]

It's weird that the same code psutil.net_io_counters() works on my dev machines(win7 x64) but doesn't work on some other machines that has the same OS as the title says.
I've done some investigation that the NIC on the failed system seems to be nothing abnormly, and it has about 20Mbps network io though one NIC.
Is it something relates to runtime?

Python version: 3.4.2

More investigation below:

when psutil.net_io_counters() gets called, it just returns me the value(600, 608), ignore the above(4251604250, 3657561882), I've studied the related code and doubt the reason of this bug is probably the dirty hack

[EvinceMoi]

now I'm pretty sure that the problem is caused by the NIC name which is not all-regular-ascii-characters composed, after changing the NIC name to plain ascii characters, it works like a charm.

The dirty hack actually not work well(maybe sometimes return the wrong data), I'm sorry that I'm not good at character codec manipulation and cannot contribute, hope someone else to fix it.

OK, I think I have fixed this in ac0da3f. Are you able to compile psutil on Windows and tell me if the issue is actually fixed?

[EvinceMoi]

Tried but couldn't work it out, failed to build psutil just like what you mentioned in INSTALL.rst, using win7 64 bit, vs2013, python 3.4 64bit

If you give me your email I can send you a pre-compiled exe installer for Python 3.4 64 bit.

New releases/installers were released in the meantime. I think this should have already been fixed by now. Closing.
