Crashes with malformed UTF-8 sequences in process command lines

[nicolargo]

Hi, a Glances' user report me an issue on the process command line with malformed UTF8 chars. See complete report here: nicolargo/glances#391

Extract:

 File "/usr/lib/python3.4/site-packages/psutil/__init__.py", line 551, in cmdline
    return self._proc.cmdline()
  File "/usr/lib/python3.4/site-packages/psutil/_pslinux.py", line 694, in wrapper
    return fun(self, *args, **kwargs)
  File "/usr/lib/python3.4/site-packages/psutil/_pslinux.py", line 771, in cmdline
    return [x for x in f.read().split('\x00') if x]
  File "/usr/lib/python3.4/codecs.py", line 313, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc3 in position 61: unexpected end of data

Can you have a look on it ?

Hey there, sorry for the late reply. I think psutil is doing the right thing in letting that kind of exception propagate. It should be up to the app (e.g. glances) to decide what to do in that situation. For the record, I think it's likely that the OP problem is related to the terminal using a locale different than UTF-8. I'm going to close this out as won't fix.
