chardet is a universal character encoding detector in python. It can find the encoding of a file also provides a confidence score of the encoding. To have chardet in your environment, install chardet with your package manager. With pip it would look like
pip install chardet
Once chardet is installed, finding encoding of a file is very simple (if data.txt is a file)
It comes back with "data.txt: ascii with confidence 1.0"
You can provide multiple files also to th chardet
chardetect data.txt chinese.txt
It comes back with
data.txt: ascii with confidence 1.0
chinese.txt: utf-8 with confidence 0.99
Integrating chardet in a pthon program to find the encoding is as follows:
file_name = 'data.txt'
result = chardet.detect(file_name)
print("Encoding: " + result['encoding'] + " Confidence " + str(result['confidence']))
