Run this code to help determine if it is a compiler or console issue:

public static void main(String[] args) throws Exception {
    String s = "¿";
    printHex(Charset.defaultCharset(), s);

    Charset utf8 = Charset.forName("UTF-8");
    printHex(utf8, s);
}

public static void printHex(Charset encoding, String s)
        throws UnsupportedEncodingException {
    System.out.print(encoding + "\t" + s + "\t");

    byte[] barr = s.getBytes(encoding);
    for (int i = 0; i < barr.length; i++) {
        int n = barr[i] & 0xFF;
        String hex = Integer.toHexString(n);
        if (hex.length() == 1) {
            System.out.print('0');
        }
        System.out.print(hex);
    }
    System.out.println();
}

If the encoded bytes for UTF-8 are different on each platform (it should be c2bf), it is a compiler issue.

If it is a compiler issue, replace "¿" with "\u00bf".
