        StringBuilder sb = new StringBuilder();
        int i = -1;
        int pos = 0;

        while ((i = utfString.indexOf("\\u", pos)) != -1) {
            sb.append(utfString.substring(pos, i));
            if (i + 5 < utfString.length()) {
                pos = i + 6;
                sb.append((char) Integer.parseInt(utfString.substring(i + 2, i + 6), 16));
            }
        }
        sb.append(utfString.substring(pos));
