Hello @magician.kim Seems to be an issue with your korean encoding, as far as I have seen searching a bit, jruby doesn't support that encoding [jruby supported enconding list](https://github.com/jruby/jcodings/blob/master/src/org/jcodings/EncodingList.java). I have search a bit more and it may work changing your codepage in that terminal/cmd with _chcp_ command Please could you try the following? ``` chcp 65001 logstash-plugin list ``` 65001 seems to be the codepage for UTF8 according to [https://ss64.com/nt/chcp.html](https://ss64.com/nt/chcp.html) I dont use korean enconding so I'm not able to reproduce the issue and help you better. I hope this help 🙂 --- _[View the full topic](https://discuss.elastic.co/t/unknown-encoding-name-error/188182)._
