java字符编码实验
import java.io.IOException;
import java.nio.charset.Charset;
import java.util.ArrayList;
import java.util.List;
import java.util.Set;
public class Test {
/**
* @param args
* @throws IOException
*/
public static void main(String[] args) throws IOException {
String str = "Hello台灣-台湾-중국어123-!@#-,./";
//String str = "Hello台灣-台湾123-!@#-,./";
Set<String> charSetKey = Charset.availableCharsets().keySet();
List<String> supportChinaCharsetList = new ArrayList<String>();
for (String charSet : charSetKey) {
try {
String result = new String(str.getBytes(charSet), charSet);
System.out.println(charSet+": " + result);
if (result.equals(str)) {
supportChinaCharsetList.add(charSet);
}
} catch (Exception e) {
System.out.println(charSet + " UnsupportedEncoding");
}
}
System.out.println(supportChinaCharsetList);
}
static void print(byte[] bytes) {
for (byte b : bytes) {
System.out.print(b);
}
System.out.println();
}
}
运行结果如下：

再看下面这个例子，如果大家把这个弄清楚，编码问题应该不是问题了
