How to type unicode character via robot in cross platform way ? I've seen solutions to this but only works on Windows eg: How to make the Java.awt.Robot type unicode characters? (Is it possible?), Is there a way to do this on Linux and Mac ?
If it's your goal to write something into an input field for example, this could probably work:
// Set desired character
String c = "ä";
StringSelection selection = new StringSelection(c);
// Copy it to clipboard
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
clipboard.setContents(selection, null);
// Paste it
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_CONTROL);
Basically simulating a copy paste, but it will delete your current clipboard content, unless you save it. Under Mac OS you want to use VK_META instead of VK_CONTROL. Also, this will not work if you really have to simulate the keypress itself, only if you want to output it.
