Java JSOUP 连接超时问题及乱码问题求助

[sandman511]

问题 1：已经设置了超时时间为 30 秒 且 JSOUP 默认超时时间为 30S，为什么输出的超时时间是 20 秒
问题 2：IDEA 已经加了 JVM 参数 && gradle 也加了 UTF-8 的编译方式，为什么还是会有乱码？且并不是全乱码，仅仅最后一个中文字符乱码，感觉跟句末的空格有联系？（同样的配置方法 本来用的 IDEA 正式版 刚刚换了社区版 正式版我 gradle 都没设定编译方式都可以正常输出）

        long t1 = System.currentTimeMillis();
        Document document = null;
        try {
            document = Jsoup.connect(URL)
                    .cookies(COOKIES).timeout(30000).post();
        } catch (IOException e) {
            long t2 = System.currentTimeMillis() - t1;
            System.out.println("连接失败，连接时间 " + t2 + " ms");
            e.printStackTrace();
        }

输出

连接失败，连接时�? 19085 ms

jsoup 的 connectTimeout 是传入的 30s，而 readTimeout 是 30 / 2 = 15s，这里应该是握手完成了然后收不到数据包超时吧，所以是 15s + 握手延迟。
我这边测下来一直在 16s ~ 22s 徘徊。
