This SO post may help you:
How to print chinese characters to the windows console correctly?[^]
Technically, there is nothing you can do from code; this is just a matter of Windows Console's configuration.

My requirement is to store the message(doesn't matter chinese or any other characters) to a file
<prev>
String test = "hello.."+"测试，收到不用理会";
com.fasterxml.jackson.databind.ObjectMapper mapper = new com.fasterxml.jackson.databind.ObjectMapper();
mapper.writeValue(new File("C:\\testpayload\\transformed.json"), test);

Is it possible to set encoding to com.fasterxml.jackson.databind.ObjectMapper.writeValue()?

This SO post delas with that:
Jackson ObjectMapper with UTF-8 encoding?[^]
If UTF-8 doesn't fit, UTF-16 should.
