> Headers in a Kafka Record are expressed as byte[], and it is quite common to convert such headers to String. 
> It would be nice to provide a ready to use byte[] to String header deserializer instead, something like:
> {code:java}
> import java.nio.charset.Charset;
> import java.nio.charset.StandardCharsets;
> import java.util.Objects;
> import org.apache.camel.component.kafka.serde.KafkaHeaderDeserializer;
> public class ToStringHeaderDeserializer implements KafkaHeaderDeserializer {
>     private Charset charset = StandardCharsets.UTF_8;
>     public Charset getCharset() {
>         return charset;
>     }
>     public void setCharset(Charset charset) {
>         this.charset = Objects.requireNonNull(charset);
>     }
>     @Override
>     public Object deserialize(String key, byte[] value) {
>         return new String(value, this.charset);
>     }
> }
> {code}
