It seems like the data in your database column is in a different encoding or format, and when it's synced to the destination, it's being transformed or interpreted differently. This could be due to the way Airbyte handles certain data types or encodings during the sync process. Unfortunately, I don't have enough information from the provided extracts to give you a confident answer about the exact reason for this transformation. I recommend checking the Airbyte documentation for more information on data type handling and transformations:
