UnicodeEncodeError [RESOLVED]; RuntimeError: Event loop is closed [OPEN]

[bc2014]

Upon running the scipt, I got 2 errors:

1. UnicodeEncodeError: 'charmap' codec can't encode character <some-character> in position <some-position>: character maps to <undefined>
   SOLUTION: add following parameter to output_file.write_text(...): encoding="utf-8"

2. RuntimeError: Event loop is closed
   Did anyone resolve this error?
