将InputStream读取为UTF-8

Question

我正在尝试text/plain逐行从Internet 上读取文件。我现在拥有的代码是：

URL url = new URL("http://kuehldesign.net/test.txt");

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));

LinkedList<String> lines = new LinkedList();

String readLine;

while ((readLine = in.readLine()) != null) {

    lines.add(readLine);

}

for (String line : lines) {

    out.println("> " + line);

}

我正在使用文件test.txt包含¡Hélló!，以测试编码。

当我查看OutputStream（out）时，看到的是> ¬°H√©ll√≥!。我不相信这是有问题的，OutputStream因为我可以做到out.println("é");没有问题。

对于InputStream作为UTF-8的阅读形式有什么想法吗？谢谢！

Answer 1

解决了我自己的问题。这行：BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));需要是：BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"));或从Java 7开始：BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), StandardCharsets.UTF_8));

String file = "";try {&nbsp; &nbsp; InputStream is = new FileInputStream(filename);&nbsp; &nbsp; String UTF8 = "utf8";&nbsp; &nbsp; int BUFFER_SIZE = 8192;&nbsp; &nbsp; BufferedReader br = new BufferedReader(new InputStreamReader(is,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; UTF8), BUFFER_SIZE);&nbsp; &nbsp; String str;&nbsp; &nbsp; while ((str = br.readLine()) != null) {&nbsp; &nbsp; &nbsp; &nbsp; file += str;&nbsp; &nbsp; }} catch (Exception e) {}尝试这个，.. ：-）

每当发现一个特殊字符将其标记为^时，我都会遇到相同的问题。为了解决这个问题，我尝试使用以下编码：ISO-8859-1BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("txtPath"),"ISO-8859-1"));while ((line = br.readLine()) != null) {}我希望这可以对任何看到此帖子的人有所帮助。
