一、1,UTF編碼 -?2,ISO解碼 -?3,UTF編碼 -?4,ISO解碼

String ISO = "ISO-8859-1";
String UTF = "UTF-8";
String GBK = "GBK";
String string = "你好";
byte[] bytes = string.getBytes(UTF);
//1,UTF編碼
for(byte b : bytes)
System.out.print(b + " ");
//-28 -67 -96 -27 -91 -67
string = new String(bytes,ISO);
//2,ISO解碼
System.out.println(string);
//結果為6個"?"
bytes = string.getBytes(UTF);
//3,UTF編碼
for(byte b : bytes)
System.out.print(b + " ");
//-61 -92 -62 -67 -62 -96 -61 -91 -62 -91 -62 -67(6個?編碼為12個UTF)
string = new String(bytes,ISO);
//4,ISO解碼
System.out.println("結果:"+string);
//結果:?¤??????????
