给你一个字符串，怎样获取它是按那种字符集编码的

Question

不同的字符集,它应该有一个分配的编码范围吧?去Unicode标准的主页上看看吧.忘了是谁订的了.

以下//后面的是运行于windwos2K server 中文dos窗口的结果,javac没有带参数-encodeing
try{ 
 System.out.println("朱镕基");//朱镕基
 System.out.println("朱镕基".getBytes());//[B@ad3ba4 //请问这里的默认编码到底是什么？本机打印的系统属性中file.encodeing=GBK
 System.out.println("朱镕基".getBytes("GBK"));//[B@126b249
System.out.println("朱镕基".getBytes("GB2312"));//[B@1690726 
System.out.println("朱镕基".getBytes("ISO8859_1"));//[B@9931f5
System.out.println();
System.out.println(new String("朱镕基".getBytes()));//朱镕基
System.out.println(new String("朱镕基".getBytes(),"GBK"));//朱镕基 
System.out.println(new String("朱镕基".getBytes(),"GB2312"));//朱?F基 
System.out.println(new String("朱镕基".getBytes(),"ISO8859_1"));//?ìéF?ù 
System.out.println();
System.out.println(new String("朱镕基".getBytes("GB2312")));//朱?基 
System.out.println(new String("朱镕基".getBytes("GBK")));//朱镕基 
System.out.println(new String("朱镕基".getBytes("GB2312"),"GB2312"));//朱?基 
System.out.println(new String("朱镕基".getBytes("GB2312"),"ISO8859_1"));//?ì??ù
System.out.println();
System.out.println(new String("朱镕基".getBytes("ISO8859_1")));//??? 
System.out.println(new String("朱镕基".getBytes("ISO8859_1"),"GBK"));//??? 
System.out.println(new String("朱镕基".getBytes("ISO8859_1"),"GB2312"));//??? 
System.out.println(new  String("朱镕基".getBytes("ISO8859_1"),"ISO8859_1"));//??? 
} 
catch(Exception e){ 
e.printStackTrace(); 
}
