<ul><li>When using SeaTunnel 2.3.9 to sync data from Oracle to Doris, you may encounter garbled characters—especially if the Oracle database uses the ASCII character set.</li><li>The issue stems from how SeaTunnel reads data from Oracle. If Oracle is using a character set like ASCII, and you're syncing to Doris (which expects proper UTF-8 or other compatible encodings), Chinese characters can become unreadable.</li><li>The key is to intercept and re-encode the data when it is read from the Oracle ResultSet.</li><li>By adding a simple charset-switching mechanism and tweaking the JDBC source implementation, you can eliminate garbled characters when syncing Oracle data to Doris using SeaTunnel.</li></ul>
