'cp932' codec can't encode character '©' in position 3337: illegal multibyte sequence
Exception commonly encountered
when running Python on Japanese version of Windows,
but almost never observed on Linux.
Verify the point below
before delving into the intricacies of encoding and decoding of python.
And note to myself.
At the line corresponding to the stack trace,
typical print line is written like this.
print(some_text)
When running the script from the command line and outputting directly,
it does not raise an exception.
python some_script.py
However, redirecting the output results in raising an exception.
python some_script.py > result.txt
Avoiding the convenient redirection
and opting for proper file writing with specified encoding
improves the situation,
but it may be more cumbersome.
with open(outputfilename, 'w', encoding='utf-8') as fout:
In essence, it seems that
the cause of the exception during redirection in command-line execution
was the redirect's inability to specify encoding.
