Logstash on windows what is the encoding problem?

Question

Windows

Good afternoon. Please tell me how to solve the problem with the encoding in logstash?
Introductory:
Logstash is running on Windows, FileBeat sends it logs, which is also running on Windows.
And the actual settings

input {
  tcp {
   port => "5045"
   codec => multiline {
     pattern => "^\d\d:\d\d."
     negate => "true"
     what => "previous"
   }
  }
  beats {
    port => 5046
    #codec => plain { charset => "UTF-8" }
  }
 }
output {
  stdout { codec => rubydebug }
}

and here is the result

When logstash was on ubuntu 16 everything was fine.
Please tell me where to dig so that Russian characters (located in the places of questions) are normally recognized.
