将unicode纯文本转换为公共字符串

它看起来像UTF-16编码。下面是一个转换它的方法:

public static String decode(String hexCodes, String encoding) throws UnsupportedEncodingException {
    if (hexCodes.length() % 2 != 0)
        throw new IllegalArgumentException("Illegal input length");
    byte[] bytes = new byte[hexCodes.length() / 2];
    for (int i = 0; i < bytes.length; i++)
        bytes[i] = (byte) Integer.parseInt(hexCodes.substring(2 * i, 2 * i + 2), 16);
    return new String(bytes, encoding);
}

public static void main(String[] args) throws UnsupportedEncodingException {
    String hexCodes = "005400610020007400650020007400ED0020007400FA0020003F0020003A0029";
    System.out.println(decode(hexCodes, "UTF-16"));
}

}

您的示例返回“tate:)”

Integer.parseInt(s, 16) 获取数值。把它扔给一个 char

时间:)

另一种分析方法:

 public static String mydecode(String hexCode) {
    StringBuilder sb = new StringBuilder();
    for(int i=0;i<hexCode.length();i+=4) 
      sb.append((char)Integer.parseInt(hexCode.substring(i,i+4),16));
    return sb.toString();
 }

 public static void main(String[] args)  {
    String hexCodes = "005400610020007400650020007400ED0020007400FA0020003F0020003A0029";
    System.out.println(mydecode(hexCodes));
 }
