    Description

      The language-identifier plugin uses org.apache.tika.language.LanguageIdentifier for extracting the language from the document text. There are two issues with that:

      1. LanguageIdentifier is deprecated in Tika.
      2. It does not support CJK language (and I suspect a lot of other languages - https://wiki.apache.org/nutch/LanguageIdentifierPlugin#Implemented_Languages_and_their_ISO_636_Codes), and it doesn’t even fail gracefully with them - in my experience Chinese was recognized as Italian.
