BUG Encoding string contains '-' character, problem with C40 Encoding

Hi,

I forced using C40 Encoding : context.setForce(true); The problem occurs when i run this test with “Hello-Google” or “–” :

public final class DataMatrixWriterTestCase extends Assert {

  @Test
  public void testDataMatrixImageWriter() {

    Map<EncodeHintType,Object> hints = new EnumMap<>(EncodeHintType.class);
    hints.put(EncodeHintType.DATA_MATRIX_SHAPE, SymbolShapeHint.FORCE_SQUARE);
    hints.put(EncodeHintType.FORCE_C40, true);

    int bigEnough = 64;
    DataMatrixWriter writer = new DataMatrixWriter();
    BitMatrix matrix = writer.encode("Hello-Google", BarcodeFormat.DATA_MATRIX, bigEnough, bigEnough, hints);
    assertNotNull(matrix);
    assertTrue(bigEnough >= matrix.getWidth());
    assertTrue(bigEnough >= matrix.getHeight());
  }

i got this error :

> java.lang.IllegalArgumentException: Can't find a symbol arrangement that matches the message. Data codewords: 1559

I had a deeper look at it. If you are OK with it then I will make a PR for it now.
