JavaScript校验输入的字符串是否包含特殊字符

校验在文本框输入的字符串中是否包含特殊字符串，js代码如下

function strInclude(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;
                }
            }
        }
    }
}
