I am trying to run a bq job that that does the export to GCS files, how can I make it to extract them with encoding UTF-8

the part am using to extract is:

new JobConfigurationExtract()
      .setSourceTable(sourceTableReference)
      .setDestinationFormat("CSV")
      .setDestinationUris(ImmutableList.of(destinationUri))

how can I configure this to use UTF-8 encoding?
