public static String removeFourChar(String content) {
byte[] conbyte = content.getBytes();
for (int i = 0; i < conbyte.length; i++) {
if ((conbyte[i] & 0xF8) == 0xF0) {

}
结果：
String title = "ff的范德萨分😁😁😁😁Llfldakf;dsk。f😁😁😁😁😁😁daslfjdsa;lfkjdsd'j'l'f'k'd'j'sa'l'k";
System.out.println(Test_Common2.removeFourChar(title).replaceAll("0000", ""));
//ff的范德萨分Llfldakf;dsk。fdaslfjdsa;lfkjdsd'j'l'f'k'd'j'sa'l'k
