TrayMenu can't show unicode characters

[GTOL]

Code to reproduce the problem.

FXTrayIcon icon = new FXTrayIcon(stage, App.class.getResource("image/icon.png"));
icon.show();
icon.addExitItem("退出");

FYI
Unicode text is not displayed correctly in awt Label

Great find! I think we can handle this, let me look at it a bit further, but in this day and age, there's not a lot that doesn't support Unicode. I would think that even the AWT calls that we make support this.
