Charset Normalizer


A Library that helps you read text from unknown charset encoding. This project is motivated by chardet, I’m trying to resolve the issue by taking another approach. All IANA character set names for which the Python core library provides codecs are supported.

It aims to be as generic as possible.

This library aim to assist you in finding what encoding suit the best to content. It DOES NOT try to uncover the originating encoding, in fact this program does not care about it.

By originating we means the one that was precisely used to encode a text file.


my_byte_str = 'Bonjour, je suis à la recherche d\'une aide sur les étoiles'.encode('cp1252')

We ARE NOT looking for cp1252 BUT FOR Bonjour, je suis à la recherche d'une aide sur les étoiles. Because of this

my_byte_str.decode('cp1252') == my_byte_str.decode('cp1256') == my_byte_str.decode('cp1258') == my_byte_str.decode('iso8859_14')
# Print True !

There is no wrong answer to decode my_byte_str to get the exact same result. This is where this library differ from others. There’s not specific probe per encoding table.


  • Encoding detection on a fp (file pointer), bytes or PathLike.

  • Transpose any encoded content to Unicode the best we can.

  • Detect spoken language in text.

  • Ship with a great CLI.

  • Also, detect binaries.
