这个字符是什么意思以及如何解码这些类型的字符？

Question

我收到一个带有一些特殊字符的 xml，例如这些 Pre‿charged ‿，当我解析此数据时，我无法解析。在我的 xml 中，我得到 Prex**E2x80?**Charged 或 Pre’charged 有什么方法可以对此进行编码吗？ 示例代码：

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = null;
        Document document = null;

        try 
        {
            builder = factory.newDocumentBuilder();
            document = builder.parse(xmlFile); // xml data in string format
            document.getDocumentElement().normalize();

        } 
        catch (ParserConfigurationException e) 
        {
            System.out.printf("Failed to parse XML Feed data", e);
        }

我尝试过 UTF-8、ANSII 和其他一些编码技术。 编辑 ： 读取 xml 数据如下

StringBuffer outputData = new StringBuffer();
        URL url;
        InputStream is = null;
        BufferedReader br;
        String line;

        try 
        {
            url = new URL(data_url);
            is = url.openStream();
            br = new BufferedReader(new InputStreamReader(is,"UTF-8"));
            while ((line = br.readLine()) != null) 
            {
                outputData.append(line.trim());
            }
            br.close();
        } 
        catch (MalformedURLException mue) 
        {
            LOGGER.error("MalformedURLException while fetching feed data", mue);
        } 
        catch (IOException ioe) 
        {
            LOGGER.error("IOException while fetching feed data", ioe);
        } 
        finally 
        {
            try 
            {
                if (is != null) 
                {
                    is.close();
                }
            } 
            catch (IOException ioe) 
            {
                // Silent fail
            }
        }

        return outputData.toString();
