返回中文unicode的byte字符串

工作中需要这样的功能，下面是实现代码，比如输入“朋友”，输出/u0b67/ucb53

public class UnicodeByteUtil {
public static void main(String[] args) {
UnicodeByteUtil instance = new UnicodeByteUtil();
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String line;
try {
while ((line = reader.readLine()) != null) {
if (line.trim().equals("q")) System.exit(0);
String s = instance.getBytes(line);
System.out.println("bytes:" s);
//System.out.println("line:" );
}
} catch (IOException e) {
e.printStackTrace();
}
}

String getBytes(String s) {
try {
StringBuffer out = new StringBuffer("");
byte[] bytes = s.getBytes("unicode");
for (int i = 2; i < bytes.length; i ) {
out.append("\\u");
String str = Integer.toHexString(bytes[i 1] & 0xff);
for (int j = str.length(); j < 2; j ) {
out.append("0");
}
out.append(str1);
}
return out.toString();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
return null;
}
}
}
