[SalesForce] File encoding Data Extract – Marketing Cloud

we exported few files (.CSV, .ZIP) from Marketing Cloud into SFTP folder using Data Extract and File Transfer as activities.
We noticed that files' encoding is 'UCS-2 LE BOM' and not 'UTF-8' as expected.
Where can i change file encoding in Marketing Cloud Account?
Thanks,

You can ask to the support (via ticket) to enable the tar.gz compression. Note: it will change the date formatting of the extracted data too though.
