                            .execute();

        System.out.println(url);
        System.out.println("PASSED");

推荐答案

编码没有错误，这里的问题是复合unicode&预先组合的字符Ñ"的unicode可以以两种方式显示，它们看起来相同但确实不同

The encoding is not wrong, the problem here is composite unicode & precomposed unicode of character "Ñ" can be displayed in 2 ways, they look the same but really different

precomposed unicode: Ñ           -> %C3%91
composite unicode: N and ~       -> N%CC%83

我强调两者都是正确的，这取决于您想要哪种类型的unicode:

I emphasize that BOTH ARE CORRECT, it depends on which type of unicode you want:

String normalize = Normalizer.normalize("Ñ", Normalizer.Form.NFD);
System.out.println(URLEncoder.encode("Ñ", "UTF-8")); //%C3%91
System.out.println(URLEncoder.encode(normalize, "UTF-8")); //N%CC%83
