             Project: Flink
          Issue Type: Improvement

    Affects Versions: 1.10.0
            Reporter: Benchao Li


This is a known issue for jackson: [https://github.com/FasterXML/jackson-core/issues/223]

You can see more details: [https://github.com/FasterXML/jackson-core/blob/master/src/main/java/com/fasterxml/jackson/core/json/UTF8JsonGenerator.java#L2105]

 

And I also encountered this issue in my production environment. I've figured out a solution to solve this issue. Java's String.getBytes() can deal with UTF-8 encoding well. So we can do it like this:

{{mapper.writeValueAsString(node).getBytes()}} instead of 

{{mapper.writeValueAsBytes(node)}}
