Notes about unicode handling in psutil
======================================

Starting from version 5.3.0 psutil adds unicode support, see:
https://github.com/giampaolo/psutil/issues/1040
The notes below apply to *any* API returning a string such as
process exe(), cwd() or username():

* all strings are encoded by using the OS filesystem encoding
  (sys.getfilesystemencoding()) which varies depending on the platform
  (e.g. "UTF-8" on macOS, "mbcs" on Win)
* no API call is supposed to crash with UnicodeDecodeError
* instead, in case of badly encoded data returned by the OS, the
  following error handlers are used to replace the corrupted characters in
  the string:
    * Python 3: sys.getfilesystemencodeerrors() (PY 3.6+) or
      "surrogatescape" on POSIX and "replace" on Windows
    * Python 2: "replace"
* on Python 2 all APIs return bytes (str type), never unicode
* on Python 2, you can go back to unicode by doing:

    >>> unicode(p.exe(), sys.getdefaultencoding(), errors="replace")

For a detailed explanation of how psutil handles unicode see #1040.

Tests
=====

List of 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
