What steps will reproduce the problem?  
1. Rename any NIC's connection to something with unicode characters, like 
"Połączenie lokalne" - default name in Polish version of Windows
2. Simply try get stats 

What is the expected output?  
Stats for every NIC 

What do you see instead?  
Stats only for NICs named without any unicode characters 

What version of psutil are you using? What Python version?  
Problem occurs both on Python 2.3.7 and 3.3, x86 

On what operating system? Is it 32bit or 64bit version?  
Windows 7 Pro x64 SP1 Please provide any additional information below.

I tried to look into this but so far I wasn't able to find any solution as the 
way we're retrieving the NIC name is the one recommended by the official 
Windows documentation.

For posterity, problem is here:

Also, another note: on my Windows 7 box the NIC gets listed but its name is 
truncated after encountering the first unicode character (whereas you state it 
is not listed at all - are you sure about that?).

Yup, I'm sure. Maybe try re-encode the string or add an option to strip unicode 
characters?
In my case NICs with unicode characters simply doesn't appear in the returned 
list, they aren't counted into overall stats too.

Does ipconfig /all show the NIC?

Yes, of course.

No, sorry. I'm also pretty swamped lately because of a new job so I won't have 
time to dedicate to this issue (and psutil in general to be entirely honest).

The problem is here: 
https://code.google.com/p/psutil/source/browse/psutil/_psutil_mswindows.c?name=release-1.2.1#2260
 The Py_BuildValue able to decode only the UNICODE characters.
I made the following path to replace these characters with "_".

    while (pCurrAddresses) {
        py_nic_name = NULL;
        py_nic_info = NULL;
>   int i;
        ...
        sprintf(ifname, "%ws", pCurrAddresses->FriendlyName);
>   for (i=0; i<100; i++) {
>     if ( *(ifname+i) < 0 || *(ifname+i) > 256 ) {
>        // Replace the NON UNICODE character
>        *(ifname+i)='_';
>     }
>     if (*(ifname+i) == '\0') {
>       // end of friendly name
>       break;
>     }
>   }
        py_nic_name = Py_BuildValue("s", ifname);

@g.rodola: can you put this patch into the next release?
