前导“？” UTF-8 中的符号
有一些文件index.html（以UTF-8保存）：
<html>
<head></head>
<body>
<h1> THE TITLE </h1>
Please click <a href="url"> here </a>
<br> ... Some text... <br>
Image: <img src="nature.png"/>
<br> ... Some another text... <br>
Image2: <img src="nature2.png" />
</body>
</html>
我需要获取BODY标记内包含的所有文本，修改它，然后保存。所以我喜欢这样：
File input = new File("html/input.html");
Document doc = Jsoup.parse(input, "UTF-8", "");
Elements body = doc.select("BODY");
//do some manipulations with the data and print it
System.out.println(body.html());
结果是：
?
<h1> THE TITLE </h1> Please click
<a href="url"> here </a>
...
很好，除了开头的问号。我怎样才能避免它？ 当然，我可以从结果字符串中删除它）但我想了解怎么回事。
There is some file index.html (saved in UTF-8):
<html>
<head></head>
<body>
<h1> THE TITLE </h1>
Please click <a href="url"> here </a>
<br> ... Some text... <br>
Image: <img src="nature.png"/>
<br> ... Some another text... <br>
Image2: <img src="nature2.png" />
</body>
</html>
I need to fetch all the text containing inside the BODY tag, modify it, and save. So I do like this:
File input = new File("html/input.html");
Document doc = Jsoup.parse(input, "UTF-8", "");
Elements body = doc.select("BODY");
//do some manipulations with the data and print it
System.out.println(body.html());
The result is:
?
<h1> THE TITLE </h1> Please click
<a href="url"> here </a>
...
It's fine, except the question symbol at the begining. How can I avoid it?
Of course I can just delete it from the result string) But I would like to understand whats the matter.

首先，您需要创建一个能够理解
UTF-8的 PrintStream：然后尝试将输出重定向到文件，并查看将其读取为
UTF-8时是否仍然存在垃圾。 。如果不是，那么您的控制台根本就不是
UTF-8并且不知道如何处理它。First of all you need to make a PrintStream that understands
UTF-8:Then try to redirect output to a file and see if there's still garbage when reading it as
UTF-8.If not then your console simply isn't
UTF-8and doesn't know how to handle it.
