Mikel San Vicente created SPARK-22442:
-----------------------------------------
Summary: Schema generated by Product Encoder doesn't match case
class field name when using non-standard characters
Key: SPARK-22442
URL: https://issues.apache.org/jira/browse/SPARK-22442
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.2.0, 2.1.2, 2.0.2
Reporter: Mikel San Vicente
Priority: Normal
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)
```
