I did not like the idea of single prober per encoding table that could lead to hard coding specifications. I wanted to challenge the existing methods of discovering originating encoding. You could consider this issue as obsolete because of current norms : You should indicate used charset encoding as described in standards But the reality is different, a huge part of the internet still have content with an unknown encoding. (*One could point out subrip subtitle (SRT) for instance*) This is why a popular package like Requests embed Chardet to guess apparent encoding on remote resources. https://github.com/Ousret/charset_normalizer https://pypi.org/project/charset-normalizer Charset Normalizer . *A first PoC.
