Handle the ^ and ê key press with JavaFX - javafx

Question

From a JavaFX application, I would like to be able to type letters like ê, ô, etc. Using linux and my keyboard mapping, it's done with dead chars (ie. typing ^, then e).
I also tried to handle the ^ key directly. According to the Javadoc, the key code for ^ is KeyCode.CIRCUMFLEX.
Here is a simple key press test application, which print the name (e.getCode().getName()) and and the text (e.getText()) of a key each time a key is pressed:
package sample;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception {
BorderPane pane = new BorderPane();
Label label = new Label("Type some text...");
pane.setLeft(label);
Scene scene = new Scene(pane, 200, 40);
primaryStage.setScene(scene);
primaryStage.show();
scene.setOnKeyPressed(e -> label.setText("name: " + e.getCode().getName() + "\ntext: " + e.getText()));
}
public static void main(String[] args) {
launch(args);
}
}
When I run this application:
I can't display character requiring dead letters (like ê);
The code for the key ^ is UNDEFINED, so I can't handle this key with something like if(e.getCode() == KeyCode.CIRCUMFLEX).
I am wrongly using key events or is it a JavaFX issue? I use Ubuntu 16.04 and Java8.

One line with KeyEvent(using KeyTyped Event)💢
[Works both for the keyboard i use which needs Shift+6 to print ^]:
scene.addEventFilter(KeyEvent.KEY_TYPED,
event -> label.setText("name: " + event.getCharacter() + "\ntext: " + event.getCharacter()));
So to detect if ^ is typed you can use inside the event:
if(event.getCharacter().equals("^"){
.....
}
