基本能过滤大部分的ios,安卓,微信emoji表情
有很多别的帖子搜出来很多有bug,有些表情是不能过滤的
类似于这个判断,过滤成功率有点低
private static boolean isEmojiCharacter(char codePoint) {//不能完整判断
return (codePoint == 0x0) ||
(codePoint == 0x9) ||
(codePoint == 0xA) ||
(codePoint == 0xD) ||
((codePoint >= 0x20) && (codePoint <= 0xD7FF)) ||
((codePoint >= 0xE000) && (codePoint <= 0xFFFD)) ||
((codePoint >= 0x10000) && (codePoint <= 0x10FFFF));
}
*********************下面的方法过滤率就比较高了*********************
