java将字符串从ansi/十六进制字符串转换为unicode

Question

我对字符串转换器有问题

我从url中读取内容

http://suggestqueries.google.com/complete/search?client=firefox&hl=us&ds=yt&q=spinner

控制台中的结果是

[“纺纱工”，“纺纱工技巧”，“纺纱工烦躁”，“纺纱工越南”，“纺纱工技能”，“纺纱工玩具”，“纺纱工烦躁玩具”，“纺纱工vn”，“纺纱工手”，“纺纱工vi\u1EC7t nam”]

它包含字符串“spinner vi\u1EC7t nam”，但当操作系统读取它时，我看到“vi”ệ“南”

问题是我如何阅读api的内容才能看到“vi”ệ因此，t nam

下面是我的原始代码

```

    URL url = new URL("http://suggestqueries.google.com/complete/search?client=firefox&hl=us&ds=yt&q=spinner");
    URLConnection urlConnection = url.openConnection();
    urlConnection.connect();
    InputStream inputStream = urlConnection.getInputStream();

    InputStreamReader reader      = new InputStreamReader(inputStream);
    BufferedReader bufferedReader = new BufferedReader(reader);
    String line;
    while((line=bufferedReader.readLine()) != null){
        System.out.println(line);
    }
    bufferedReader.close();
    reader.close();

```

试试这个

static final Pattern UNICODE = Pattern.compile("\\\\u([0-9a-fA-F]{4})");

static String decodeUnicodeEscape(String s) {
    Matcher m = UNICODE.matcher(s);
    StringBuffer sb = new StringBuffer();
    while (m.find())
        m.appendReplacement(sb,
            String.valueOf((char)Integer.parseInt(m.group(1), 16)));
    m.appendTail(sb);
    return sb.toString();
}

及

System.out.println(decodeUnicodeEscape(" vi\\u1EC7t nam"));

结果

 việt nam
