UTF-8 encoding issue special characters like 'é' not replicated properly
提问by shilpa
I am trying to encode a string with special characters like 'é' using below mentioned code then it is not replicated properly...
我正在尝试使用下面提到的代码对带有特殊字符（如“é”）的字符串进行编码，然后它没有被正确复制......
String Cdata="MARIE-HéLèNE";
byte sByte[]=Cdata.getBytes();
Cdata= new String(sByte,"UTF-8");
System.out.println(Cdata);
expected output: MARIE-HéLèNE but instead output: MARIE-HE coming
预期输出：MARIE-HéLèNE 而是输出：MARIE-HE come

First thing is that you need to make sure that your source file is actually stored as UTF-8- see @Ankur's answer for a good explanation.
第一件事是您需要确保您的源文件实际上存储为UTF-8- 请参阅@Ankur 的回答以获得一个很好的解释。
Then, you also need to provide an encoding when calling getBytes()on Stringto retrieve the byte array:
然后，您还需要提供编码时调用getBytes()上String检索字节数组：
byte sByte[] = Cdata.getBytes("UTF-8");
If you call String.getBytes()with no encoding, the platform`s default encodingis used, which can be (almost) anything. See also java.lang.String.getBytes():
如果您String.getBytes()不使用编码进行调用，则使用平台的默认编码，它可以（几乎）是任何内容。另见java.lang.String.getBytes()：
Encodes this String into a sequence of bytes using the platform's default charset
使用平台的默认字符集将此字符串编码为字节序列
With that, the following SSCCE properly prints the expected output for me (note: took identifiers from question, not adjusted to coding conventions):
有了这个，下面的 SSCCE 正确地为我打印了预期的输出（注意：从问题中获取标识符，没有调整到编码约定）：
import java.io.UnsupportedEncodingException;
public class Encoding {
public static void main(String[] args) throws UnsupportedEncodingException {
String Cdata = "MARIE-HéLèNE";
byte sByte[] = Cdata.getBytes("UTF-8");
Cdata = new String(sByte,"UTF-8");
System.out.println(Cdata);
}
}

You need to tell eclipse to use UTF-8 for its stdout console. You can set that by Window > Preferences > General > Workspace > Text File Encoding.
您需要告诉 eclipse 为其标准输出控制台使用 UTF-8。您可以通过 Window > Preferences > General > Workspace > Text File Encoding 进行设置。
