Java字符串找出4个字节长度的字符

不解释，直接上代码：
由于Iteye代码贴四个字节的ＵＴＦ－８字符出错，特能图的方式发布几个特殊字符：



public class Byte4Check {public static void main(String args[]) throws UnsupportedEncodingException {String nickName = "12葫";byte[] t = nickName.substring(0, 1).getBytes("UTF-8");for (byte tt : t) {System.out.println(tt);}System.out.println("====================");byte[] t1 = nickName.getBytes("UTF-8");for (int i = 0; i < t1.length;) {byte tt = t1;if (CharUtils.isAscii((char) tt)) {byte[] ba = new byte[1];ba[0] = tt;i++;String result = new String(ba);System.out.println("1个字节的字符");System.out.println("字符为：" + result);}if ((tt & 0xE0) == 0xC0) {byte[] ba = new byte[2];ba[0] = tt;ba[1] = t1[i+1];i++;i++;String result = new String(ba);System.out.println("2个字节的字符");System.out.println("字符为：" + result);}if ((tt & 0xF0) == 0xE0) {byte[] ba = new byte[3];ba[0] = tt;ba[1] = t1[i+1];ba[2] = t1[i+2];i++;i++;i++;String result = new String(ba);System.out.println("3个字节的字符");System.out.println("字符为：" + result);}if ((tt & 0xF8) == 0xF0) {byte[] ba = new byte[4];ba[0] = tt;ba[1] = t1[i+1];ba[2] = t1[i+2];ba[3] = t1[i+3];i++;i++;i++;i++;String result = new String(ba);System.out.println("4个字节的字符");System.out.println("字符为：" + result);}}}}
