如何将字符串转换为字节并返回
为了转换字符串，我将其转换为字节，如下所示： byte[] nameByteArray = cityName.getBytes();
为了转换回来，我做了： String returnedString = new String(nameByteArray); 这显然不起作用。我该如何将其转换回来？
For converting a string, I am converting it into a byte as follows:byte[] nameByteArray = cityName.getBytes();
To convert back, I did: String retrievedString = new String(nameByteArray); which obviously doesn't work. How would I convert it back?

The solution is to explicitly use an encoding that can represent all characts, such as UTF-8:
