toBytes
Converts a String to byte[], using the given character set. For example, given a schema such as:
{ "type": "record", "name": "events", "fields": [ { "name": "name", "type": "string" }, { "name": "s", "type" : "string"} ] }
and a record such as:
{ "name" : "My Event", "s" : "Hello World!" }
The following record path would convert the String field into a byte array using UTF-16 encoding:
toBytes( /s, "UTF-16")
