ANN: psutil 5.3.0 with full unicode support is out

[Giampaolo Rodola']

Mmm thanks for pointing this out. I don't have a Windows machine to test
this against right now but it seems you're right and there's something
wrong in my example (which is what I recommend in the official doc BTW, so
it needs to be fixed).

That aside, do you think the rest of my reasoning makes sense? I mean
returning str all the time and provide a strategy to convert the string to
unicode in Python 2?
