将InputStream读取为UTF-8

Question

我试图text/plain通过互联网逐行读取文件.我现在的代码是:

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);
}

该文件test.txt包含¡Hélló!,我正在使用它来测试编码.

当我查看OutputStream(out)时,我将其视为> ¬°H?©ll??!.我不相信这是一个问题,OutputStream因为我可以out.println("é");没有问题.

阅读的任何想法都形成InputStreamUTF-8？谢谢!

Answer 1

解决了我自己的问题.这一行:

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

需要是:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"));

或者从Java 7开始:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), StandardCharsets.UTF_8));

Answer 2

String file = "";

try {

    InputStream is = new FileInputStream(filename);
    String UTF8 = "utf8";
    int BUFFER_SIZE = 8192;

    BufferedReader br = new BufferedReader(new InputStreamReader(is,
            UTF8), BUFFER_SIZE);
    String str;
    while ((str = br.readLine()) != null) {
        file += str;
    }
} catch (Exception e) {

}

试试这个,.. :-)

Answer 3

每当发现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-8859-1

BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("txtPath"),"ISO-8859-1"));

while ((line = br.readLine()) != null) {

}
