title: How to correct Greek accented characters in a TextField
body: <p>The problem I am facing is when I have an input (TextField, TextArea, etc.) and I am trying to insert some Greek words which contain accented characters. Words like " Γάτα " (cat) works fine. Unfortunately, I am unable to <strong>type</strong> words like " Ταϊτή " (Tahiti). If I try to copy and paste it or hard code it, it is working fine, but when I try to write the word using the combination of</p>
  
  <p>Shift + ';' + ι</p>
  
  <p>which should produce the 'ϊ', instead I am getting '¨ι'</p>
  
  <p>Here is an example :</p>
  
  <pre><code>import javafx.application.Application;
  import javafx.geometry.Insets;
  import javafx.geometry.Pos;
  import javafx.scene.Scene;
  import javafx.scene.control.TextField;
  import javafx.scene.layout.VBox;
  import javafx.stage.Stage;
  
  public class Example extends Application {
  
      public static void main(String[] args) {
          launch(args);
      }
  
      @Override
      public void start(Stage stage) throws Exception {
  
          VBox mainBox = new VBox(10);
          mainBox.setPadding(new Insets(20));
          mainBox.setAlignment(Pos.CENTER);
  
          // Ταϊτή = Tahiti
          TextField field1 = new TextField("Ταϊτή");
          TextField field2 = new TextField();
  
          mainBox.getChildren().add(field1);
          mainBox.getChildren().add(field2);
  
          field1.setStyle("-fx-font-size:24px");
          field2.setStyle("-fx-font-size:24px");
  
          stage.setScene(new Scene(mainBox));
          stage.show();
      }
  }
  </code></pre>
  
  <p>And the image below show what I have as a result when i type the word myself</p>

  <p>Installed JRE : jre1.8.0_221</p>
  
  <p>Installed JDK : jdk1.8.0_221</p>
  
  <p>To exclude the IDE (Eclipse) as a cause of the problem, I tested this behavior on SceneBuilder with just an AnchorPane and a TextField and I had the same issue there as well. But for the sake of argument, I have the editor and all the settings in the Eclipse to use the encoding UTF-8.</p>
  
  <p><strong>So I would like to ask: Is this a bug of the current JRE/JDK and if so, is there a well-known solution I could use or I should just use a Listener to catch the input and correct it myself?</strong></p>
  
  <p><strong>Edit :</strong> As Sedrick point it out I could use the combination of alt + 0 2 3 9 but this is going to produce a different kind of letter which is similar to the Greek one but not the same. Look the image below. Unfortunately this is not the behavior than my client wants to, because the correct way to type it ( in Greek keyboards ) is with the : Shift + ';' + ι  , where the 'ι' is the English letter 'i'.</p>

  <p><strong>Edit 2:</strong> Also I could hack my way around it by using the code below but if i decided to do so, I must do it for all of my TextFields which is something i would like to avoid. Otherwise I should create a "dummy" CustomTextField class which will extends the TextField and implement the hack there, then I could replace all the TextField references on my project with the CustomTextField.</p>
  
  <pre><code>field2.setTextFormatter(new TextFormatter&lt;&gt;(c -&gt; {
      String text = c.getControlNewText();
  
      if (text.contains("¨ι") || text.contains("¨Ι")) { 
  
          // In order to "catch" a word with multiple wrong characters
          // for example if someone tries to copy/paste, I will use
          // the replaceAll() method
          text = text.replaceAll("¨ι", "ϊ");
          text = text.replaceAll("¨Ι", "Ϊ"); 
  
          // update the field 
          field2.setText(text);
  
          // correct the caret and anchor positions
          c.setCaretPosition(c.getCaretPosition() - 1);
          c.setAnchor(c.getCaretPosition());
  
          c.setText(""); // consume change because we already update it
      }
      return c;
  }));
