Description

Installed pywikibot using pip (Metadata-Version: 2.0, Name: pywikibot, Version: 2.0rc5)
when running my own script with Python 3.5.1 containing

import pywikibot

I get

when I move the script to "core" folder where pwb.py etc. is then it works

I don't understand how moving can solve this issue.

The main problem here is that Python thinks the console uses the cp437 charset, which is the IBM PC charset, rather than the cp895 Czech charset that one would expect on a Czech machine. We cannot use pywikibot.output (or pywikibot.exception) here yet, so I think we should just print repr(e) instead, as that would always be an ascii-only (albeit maybe not completely readable) form.

I dont have a good explanation, but I cleaned my system of all old python installations, cleaned out the system variables and installed python 3.5.2 and pywikibot library anew and everything now runs fine, the script executes without errors.
