EUC-KR files are not detected correctly. Charset-Normalizer 2.1.1 detected it correctly.

Notice
I hereby announce that my raw input is not :

  • Too small content (<=32 characters) as I do know that ANY charset detector heavily depends on content
  • Encoded in a deprecated/abandoned encoding that is not even supported by my interpreter

Provide the file
