Description
public void testTable() {
String sql = "select b, '中文' from test.t2 where b = a";
RelNode relNode = TestUtils.convertTable(sql);
RelToTrinoConverter relToTrinoConverter = new RelToTrinoConverter();
SqlNode expandedSql = relToTrinoConverter.convertToSqlNode(relNode);
System.out.println(expandedSql);

Research direction
Start with the testTable reproduction, especially TestUtils.convertTable(sql) and RelToTrinoConverter.convertToSqlNode(relNode). Run the example containing the Chinese literal and trace where ISO-8859-1 encoding is applied. Done means the conversion completes without the CalciteException and preserves the literal in the resulting SQL node.
