Fix consoles encoding in Python 3

[s-weigand]

Fixes #3061

---

Here is the fix for the bug described in #3061.
@PierreRaybaut as author if that piece of code should review my change and check if not I broke more than I fixed. :D

best regards Sebastian

As I wrote in issue #3061, I recommend keeping the "Setting console encoding [...] for Windows platforms" code block for Python 2.

So the right fix for me would rather be the following:

#==============================================================================
# Setting console encoding (otherwise Python does not recognize encoding)
# for Windows platforms
#==============================================================================
+if os.name == 'nt' and PY2:
-if os.name == 'nt':
    try:
        import locale, ctypes
        _t, _cp = locale.getdefaultlocale('LANG')
        try:
            _cp = int(_cp[2:])
            ctypes.windll.kernel32.SetConsoleCP(_cp)
            ctypes.windll.kernel32.SetConsoleOutputCP(_cp)
        except (ValueError, TypeError):
            # Code page number in locale is not valid
            pass
    except ImportError:
        pass

@s-weigand, please remove your last commit (we don't accept PRs with blank space changes).

Also, please don't do more commits besides the change suggested by Pierre. If things fail in our continuous integration services, we'll see how to fix them (usually that requires to restart the build, which was what I was doing).

Sorry it took my so long to remove my last commit,
i started onyl yesterday to use the github-bach and it took me some time to find out what to do to remove a allready pushed commit (rebase and force push).
Also the changed blank spaces weren't intentionally, my spyder is set to delete tailing blank spaces when saving the file.
Noob at work here :D

Ok, sorry if i sounded too bossy, I thought you knew git and all this stuff :-)

Tests are passing now, so I'm merging your work. Thanks a lot for your contribution!
