js判断字符串是否包含特殊字符和emoji表达

$scope.isEmojiCharacter=function(substring){    if(substring){        var reg = new RegExp([~##^$@%&!?%*]", 'g');        if (substring.match(reg)) {            return true;        }        for ( var i = 0; i < substring.length; i++) {            var hs = substring.charCodeAt(i);            if (0xd800 <= hs && hs <= 0xdbff) {                if (substring.length > 1) {                    var ls = substring.charCodeAt(i + 1);                    var uc = ((hs - 0xd800) * 0x400) + (ls - 0xdc00) + 0x10000;                    if (0x1d000 <= uc && uc <= 0x1f77f) {                        return true;                    }                }            } else if (substring.length > 1) {                var ls = substring.charCodeAt(i + 1);                if (ls == 0x20e3) {                    return true;                }            } else {                if (0x2100 <= hs && hs <= 0x27ff) {                    return true;                } else if (0x2B05 <= hs && hs <= 0x2b07) {                    return true;                } else if (0x2934 <= hs && hs <= 0x2935) {                    return true;                } else if (0x3297 <= hs && hs <= 0x3299) {                    return true;                } else if (hs == 0xa9 || hs == 0xae || hs == 0x303d || hs == 0x3030                    || hs == 0x2b55 || hs == 0x2b1c || hs == 0x2b1b                    || hs == 0x2b50) {                    return true;                }            }        }    }};
