Review comment:
```
Warning:Warning:line (39)implicit conversion method stringToUTF8Str should
be enabled
by making the implicit value scala.language.implicitConversions visible.
This can be achieved by adding the import clause 'import
scala.language.implicitConversions'
or by setting the compiler option -language:implicitConversions.
See the Scaladoc for value scala.language.implicitConversions for a
discussion
why the feature should be explicitly enabled.
implicit def stringToUTF8Str(str: String): UTF8String =
UTF8String.fromString(str)
