Notes about unicode handling in psutil
======================================
In psutil these are the APIs returning or dealing with a string
('not tested' means they are not tested to deal with non-ASCII strings):
* Process.cmdline()
* Process.connections('unix')
* Process.cwd()
* Process.environ()
* Process.exe()
* Process.memory_maps()
* Process.name()
* Process.open_files()
* Process.username() (not tested)
* disk_io_counters() (not tested)
* disk_partitions() (not tested)
* disk_usage(str)
* net_connections('unix')
* net_if_addrs() (not tested)
* net_if_stats() (not tested)
* net_io_counters() (not tested)
* sensors_fans() (not tested)
* sensors_temperatures() (not tested)
* users() (not tested)
* WindowsService.binpath() (not tested)
* WindowsService.description() (not tested)
* WindowsService.display_name() (not tested)
* WindowsService.name() (not tested)
* WindowsService.status() (not tested)
* WindowsService.username() (not tested)
In here we create a unicode path with a funky non-ASCII name and (where
possible) make psutil return it back (e.g. on name(), exe(), open_files(),
etc.) and make sure that:
* psutil never crashes with UnicodeDecodeError
* the returned path matches
For a detailed explanation of how psutil handles unicode see:
- https://github.com/giampaolo/psutil/issues/1040
- http://psutil.readthedocs.io/#unicode
