### System information

_No response_

### Relevant logs

```bash

```

Reproduce the report with the Spark SQL command and ../tpcds/spark-sql/all.sql using the listed Gluten-1.3 configuration. Trace the validation path for OrcReadFormat and the reported varchar types. Done means the ORC scan no longer reports these varchar columns as unsupported and forces fallback.
