UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa0 in position 10177: invalid start byte
This completely aborted offlineimap3, blocking further mail reception.
Instead, use the 'replace' error strategy in Python:
Replace with a suitable replacement character; Python will use the
official U+FFFD REPLACEMENT CHARACTER for the built-in Unicode codecs on
decoding and ‘?’ on encoding.
