Hello team,

I'm working to secure configuration on ELK stack. While creating keystore in logstash, there was an error : 'ArgumentError: invalid byte sequence in CP949'  
It also occured in v7.8.0, don't know what happens in any prevision versions.

I wonder how to solve this problem.

- environment: ELK stack 7.9.0 on Windows Server 2012 R2 (OS language : Korean)
- error messages:  
ArgumentError: invalid byte sequence in CP949
