The following command when run in BASH cleans The Raven.

cat The_Raven.txt | gawk '{print tolower($0)}' | tr -d "!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~«»"

The following Python code uses subprocess to clean “The Raven”.

command = "cat The_Raven.txt | gawk '{print tolower($0)}' | tr -d "!\"#$%&'()*+,-./:;<=>?@[\\]^_\`{|}~""
cleaned_text_from_command = subprocess.run(command, shell = True, capture_output = True, text = True, encoding = 'utf-8').stdout

Inserting «» after ~ in the above Python code causes the following error.

UnicodeDecodeError: 'utf-8' codec can't decode bytes in position 0-1: invalid continuation byte

How do I address this error?
