How to make the Java.awt.Robot type unicode characters? (Is it possible?)

by

Based on javamonkey79’s code I’ve created the following snippet which should work for all Unicode values…

public static void pressUnicode(Robot r, int key_code)
{
    r.keyPress(KeyEvent.VK_ALT);

    for(int i = 3; i >= 0; --i)
    {
        // extracts a single decade of the key-code and adds
        // an offset to get the required VK_NUMPAD key-code
        int numpad_kc = key_code / (int) (Math.pow(10, i)) % 10 + KeyEvent.VK_NUMPAD0;

        r.keyPress(numpad_kc);
        r.keyRelease(numpad_kc);
    }

    r.keyRelease(KeyEvent.VK_ALT);
}

This automatically goes through each decade of the unicode key-code, maps it to the corresponding VK_NUMPAD equivalent and presses/releases the keys accordingly.
