public class Main {
    public static void main(String[] args) {
        // 归一化前
        String str1 = "\u00C1";
        System.out.println(str1);

        String str2 = "\u0041" + "\u0301";
        System.out.println(str2);
        System.out.println(str1.equals(str2));
        System.out.println("=====after normalizer====");

        str1 = Normalizer.normalize(str1, Normalizer.Form.NFKC);
        str2 = Normalizer.normalize(str2, Normalizer.Form.NFKC);
