filename encoding error

[Robert Gierzinger]

When downloading e.g. "360° Geo Reportage" the filename cannot be encoded and thus the download does not start. This might also affect video titles with german umlaut. I used qarte version 3.1.1-0ubuntu1 on Ubuntu Xenial 64 Bit.

The error on the terminal:
Traceback (most recent call last):
  File "/usr/share/qarte/artetv.py", line 544, in start_download
    self.video_loaded = self.get_video_path(video)
  File "/usr/share/qarte/artetv.py", line 577, in get_video_path
    while os.path.isfile(path):
  File "/usr/lib/python3.4/genericpath.py", line 30, in isfile
    st = os.stat(path)
UnicodeEncodeError: 'ascii' codec can't encode character '\xb0' in position 23: ordinal not in range(128)

my assumption about german umlaut is correct: titles with umlaut cannot be writen. Also, it seems the content index cannot be written when an umlaut is in it, the error message:
12:40:31: WARNING - artetv Can't write summary: /home/username/videos/index
12:40:31: WARNING - artetv Reason: 'ascii' codec can't encode character '\xf6' in position 256: ordinal not in range(128)
