             Summary: Add documentation about how to set line feed as delimiter for csv format
                 Key: FLINK-15243
                 URL: https://issues.apache.org/jira/browse/FLINK-15243
             Project: Flink
          Issue Type: Improvement
          Components: Documentation
            Reporter: Jark Wu


As described in documentation[1], a csv format can use {{'format.line-delimiter' = '\n'}} to specify line delimiter. However, the property value is parsed into two characters "\n" , this result to reading failed. 

The correct way is using unicode as following:

{code:java}
'format.line-delimiter' = U&'\000A'   -- line feed unicode
{code}

We should update documentation for this.
