JavaFX 11 Unicode characters sequence get inversed

Question

Some of the Unicode characters are inversely rendered in JavaFX 11.

• Language: Tai Language

• Font: Pyidaungsu. Click this Link to download

• Text to render: ၸေႃႇၵျီႇ
• OS: Windows 10
• Program code guide: Getting started with JavaFx 11

• Program code:

  @Override
  public void start(Stage stage) {
      String javaVersion = System.getProperty("java.version");
      String javafxVersion = System.getProperty("javafx.version");
      Label l = new Label("Hello, JavaFX " + javafxVersion + ", running on Java " + javaVersion + ".");
      l.setFont(new Font("Pyidaungsu", 20));
  
      String problemString = "ၸေႃႇၵျီႇ";
      String fixedString = Normalizer.normalize(problemString, Normalizer.Form.NFC);
  
      Label l2 = new Label(fixedString);
      l2.setFont(new Font("Pyidaungsu", 30));
      Scene scene = new Scene(new VBox(l, l2), 640, 480);
      stage.setScene(scene);
      stage.show();
  }
  

• Compiling command : javac --module-path %PATH_TO_FX% --add-modules=javafx.controls,javafx.fxml HelloFX.java -encoding UTF-8

• Result:

The first two characters are rendered inversely. The situation is the same in JavaFX 8.
