如何正确编码此URL

Question

我正在尝试使用JSoup获取此URL

http://betatruebaonline.com/img/parte/330/ciguen%c3%91al.jpg

相反，正确的

http://betatruebaonline.com/img/parte/330/ciguen%cc%83al.jpg

我该怎么解决这个？多谢了。

private static void GetUrl()
{
    try
    {
        String url = "http://betatruebaonline.com/img/parte/330/";
        String encoded = URLEncoder.encode("CIGUEÑAL.JPG","UTF-8");
        Response img = Jsoup
                            .connect(url + encoded)
                            .ignoreContentType(true)
                            .execute();

        System.out.println(url);
        System.out.println("PASSED");
    }
    catch(Exception e)
    {
        System.out.println("Error getting url");
        System.out.println(e.getMessage());
    }
}

编码没有错，这里的问题是复合unicode&字符“-”的预组合unicode可以以两种方式显示，它们看起来相同但实际上不同

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：

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
