Wrong encoding produced by JSON_ARRAYAGG

    • Resolution: Unresolved
    • 10.11.2, 10.5, 10.6, 10.8, 10.9, 10.10, 10.11

    • JSON
    • None

    Description

      Try this query:

      select 
        json_arrayagg(json_array(ö)),
      		 
        json_arrayagg(json_object(ö, ö)), 
        json_arrayagg(ö)
      		 
      from (select 'ö' ö) ö;

      It produces

      |json_arrayagg(json_array(ö))|json_arrayagg(json_object(ö, ö))|json_arrayagg(ö)|
      		 
      |----------------------------|--------------------------------|----------------|
      		 
      |[["ö"]]                     |[{"ö": "ö"}]                    |["�"]           |

      So, when JSON is nested in JSON, then there's no encoding problem, but a string embedded directly into JSON_ARRAYAGG produces issues.
