您好，谢谢您阅读我的文章.

Hello and thank you for reading my post.

我的问题如下:我想用"javac"编译一个Java源文件，该文件是用BOM编码的UTF-8(操作系统是WinXP).

My problem is the following: I want to compile a Java source file with "javac" with this file being UTF-8 encoded with a BOM (the OS is WinXP).

以下是我的工作:

1)使用记事本"创建文件，然后选择UTF-8编码

1) Create a file with "Notepad" and choose the UTF-8 encoding

dos> notepad Test.java
"File -> Save as..."
File name   : Test.java
Save as type: All Files
Encoding    : UTF-8
Save

2)在该文件中创建一个Java类，然后像1)中一样保存文件

2) Create a Java class in that file and saved the file like in 1)

public class Test
{
    public static void main(String [] args)
    {
        System.out.println("This is a test.");
    }
}

3)可视化文件的十六进制版本(第一行)

3) Visualize the hexadecimal version of the file (first line)

dos> xxd Test.java | head -1
0000000: efbb bf70 7562 6c69 6320 636c 6173 7320  ...public class

注意: ef bb bf 是UTF-8编码的BOM(UTF-16编码的BOM是 FE FF ).

Note: ef bb bf is the UTF-8 encoded BOM (the UTF-16 encoded BOM being FE FF).

4)尝试使用"javac"编译此代码

4) Try to compile this code with "javac"

dos> javac -encoding utf8 Test.java
Test.java:1: illegal character: \65279
?public class Test
^
1 error

注意: 65279 是BOM的十进制版本.

Note: 65279 is the decimal version of the BOM.

我的问题如下:如何使此编译工作与

My question is the following: how can I make this compiling work with:
