Question

在我的JavaFX应用程序中，用户可以选择英语或印地语语言进行显示。如果我不断在英语和印地语之间切换，在一个阶段，印地语文本中的空格或特殊字符将被一些水平线替换，如屏幕截图所示。我尝试在单独的线程中设置标签文本，但没有用。是否由于缓存问题？我在设置之前尝试清除标签文字，但仍面临同样的问题。此外，禁用标签的缓存属性。有什么建议吗？

我指的是博客[Link] [1]中的'I18N实用类'。每当用户选择语言时，此类都会设置语言环境，并触发textproperty()标签。

以下是代码片段：

public class example implements Initializable {
    @FXML
    private Label dateLbl;

    public void initialize(URL url, ResourceBundle rb) {
          engBtn.setOnAction((evt) -> switchLanguage(Locale.ENGLISH));
          hnBtn.setOnAction((evt) -> switchLanguage(new Locale("hi","IN")));
          dateLbl.textProperty().bind(createStringBinding(() ->
              I18N.changeDate())); //DATE LABEL WHICH IS SHOWING WEIRD BEHAVIOUR
     }

     private void switchLanguage(Locale locale) {
         I18N.setLocale(locale);
     }
