-----------------------------------------

             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)
```
