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.
