Mikel San Vicente updated SPARK-22442:
--------------------------------------
Description:
Product encoder encodes special characters wrongly when field name contains
certain nonstandard characters.
For example for:
{{
case class MyType(`field.1`: String, `field 2`: String)
}}
we will get the following schema
{{
root
|-- field$u002E1: string (nullable = true)
|-- field$u00202: string (nullable = true)
}}
was:
