> Product encoder encodes special characters wrongly when field name contains certain nonstandard characters.
> For example for:
> {quote}
> case class MyType(`field.1`: String, `field 2`: String)
> {quote}
> we will get the following schema
> {quote}
> root
>  |-- field$u002E1: string (nullable = true)
>  |-- field$u00202: string (nullable = true)
> {quote}
> As a consequence of this issue a DataFrame with the correct schema can't be converted to a Dataset using .as[MyType]
