将字符串从 ansi/hexadecimal 字符串转换为 unicode

Question

我对字符串转换器有疑问

我阅读了来自url的内容

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

控制台中的结果是

["spinner",["spinner","spinner tricks","spinner fidget","spinner vietnam","spinner skill","spinner toy","spinner fidget toy","spinner vn","spinner hand","spinner vi\u1EC7t nam"]]

它包含字符串 "spinner vi\u1EC7t nam"，但是当按 OS 读取它时，我看到 "việt nam"

问题是我如何阅读 api 的内容以查看 "việt nam" 结果。

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();
}

和

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

结果

 việt nam
