过滤特殊字符及表情符

//这个我从逆向考虑，找出常用合法的字符，其他为非法，过滤即可
public  String stringFilter(String str) throws PatternSyntaxException {
		// 只允许字母和数字和中文//[\\pP‘’“”
		String regEx = "^[A-Za-z\\d\\u4E00-\\u9FA5\\p{P}‘’“”]+$";
		Pattern p = Pattern.compile(regEx);
		StringBuilder sb = new StringBuilder(str);

		for (int len = str.length(), i = len - 1; i >= 0; --i) {

			if (!p.matches(regEx, String.valueOf(str.charAt(i)))) {
				Toast.makeText(
						contex,
						contex.getResources().getString(R.string.emoji),
						Toast.LENGTH_SHORT);
				sb.deleteCharAt(i);
			}
		}

		return sb.toString();
	}
