----------------------------------
Summary: Support non-BMP Unicode for JsonRowSerializationSchema
Key: FLINK-16043
URL: https://issues.apache.org/jira/browse/FLINK-16043
Project: Flink
Issue Type: Improvement
Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
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)}}
