Question

场景:我想读取采用 utf-8 编码的阿拉伯数据集。每行中的每个单词都用空格分隔。

<小时/>

问题:当我阅读每一行时，输出为:

??????? ?? ???? ?? ???

<小时/>

问题:如何读取文件并打印每一行？ 欲了解更多信息，here是我的阿拉伯数据集，读取数据的部分源代码如下所示:

private ContextCountsImpl extractContextCounts(Map<Integer, String> phraseMap) throws IOException {
        Reader reader;
        reader = new InputStreamReader(new FileInputStream(inputFile), "utf-8");
        BufferedReader rdr = new BufferedReader(reader);
        while (rdr.ready()) {
            String line = rdr.readLine();
            System.out.println(line);
            List<String> phrases = splitLineInPhrases(line);
            //any process on this file
        }
}

我可以使用UTF-8阅读，你可以这样尝试吗？

public class ReadArabic {
    public static void main(String[] args) {
        try {
            String line;
            InputStream fileInputStream = new FileInputStream("arabic.txt");
            Reader reader = new InputStreamReader(fileInputStream, "UTF-8"); // leave charset out for default
            BufferedReader bufferedReader = new BufferedReader(reader);
            while ((line = bufferedReader.readLine()) != null) {
                System.out.println(line);
            }
        } catch (Exception e) {
            System.err.println(e.getMessage()); // handle all exceptions
        }
    }
}
