Don't use utf-8 in console output on windows

When running the jotta-dowload there seems to be an issue with the progress bar. The error I get is:

C:\Users\XX>jotta-download Jottacloud.pdf

    with ProgressBar(expected_size=total_size) as bar:

UnicodeEncodeError: 'charmap' codec can't encode characters in position 1-32: character maps to <undefined>

Commenting out line 229 and 233 It works perfectly.

Removing empty_char='○', filled_char='●' in Cli.py seems to fix the issue.

Ok, so the Windows command line doesn't support unicode characters.

Without really going into this, I would say that an easy fix might be to run a if platform.system()=='Windows' check, and disable the offending chars if True.
