Example 1 with Encoding

use of org.firebirdsql.encodings.Encoding in project jaybird by FirebirdSQL.

the class AbstractStatementTest method testInsertSelectUTF8Value.

@Test

    final byte[] selectVarcharFieldData = selectResult.getFieldData(0);
    final byte[] selectCharFieldData = selectResult.getFieldData(1);
    assertEquals("Length of selected varchar field data", 4, selectVarcharFieldData.length);

    String decodedVarchar = utf8Encoding.decodeFromCharset(selectVarcharFieldData);
    String decodedChar = utf8Encoding.decodeFromCharset(selectCharFieldData);
    assertEquals("Unexpected value for varchar", aEuro, decodedVarchar);
