但是在utf-8转换后我得到了这个字符串

我在java中为一些字符串进行转换我正在获得正确的输出。可能是UTF-16编码的情况，或者我做错了

以下是参考代码

String finalOutput = "";
 StringEntity inputRequest = new StringEntity(g.toJson(gt), "UTF-8");
        inputRequest.setContentType("application/json");
        postRequest.setEntity(inputRequest);
        HttpResponse response = httpClient.execute(postRequest);
        BufferedReader br = new BufferedReader(new InputStreamReader((response.getEntity().getContent())));

        String outputContent;
        while ((outputContent = br.readLine()) != null) {
            if (finalOutput == null) {
                finalOutput = outputContent;
            } else {
                finalOutput += "\n" + outputContent;
            }
        }
            byte contentByte[];

    try {
        contentByte = finalOutput.getBytes("UTF-8");
        finalOutput = new String(contentByte,"UTF-8");
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } 
    return finalOutput;

有一个带有编码的InputStreamReader 的重载版本。只有在每个平台上都可以移植。

BufferedReader br = new BufferedReader( new InputStreamReader((response.getEntity().getContent()), StandardCharsets.UTF_8)); // Or "UTF-8"

出于文体原因，最好使用StandardCharsets.UTF_8。

StringBuilder outputContent定义会更好;但正如其他人已经评论过的那样，字节和字符串之间的转换经常发生。也许考虑 ByteArrayOutputStream 。

StringBuilder sb = new StringBuilder(); String outputContent; while ((outputContent = br.readLine()) != null) { sb.append(outputContent).append('\n'); } br.close(); return= sb.toString(); // Final result, no more

日语的UTF-8
