Regex matching characters and letters

Question

I have this regex that matches letters and special characters except these

0-9\\d!@#$%^&*()_+-=?>

charcheck:function(val){
  var regex = /^[a-zA-Z][^0-9\d!@#$%^&*()_+-=?></\|}{]+$/
  return (regex.test(val)) ? true : false;
}

I wanted to add these characters to that list [] but when I do it breaks it. I have even tried ][ but that breaks also.

[ and ] are special characters in a regular expression. You can use them as literals by escaping them:

/^[a-zA-Z][^0-9\d!@#$%^&*()_+\-=?><\/\\|}{\[\]]+$/
                                           ^ ^ as literal
                              ^ - (dash) also needs to be escaped
                                    ^ ^ did you intend for these to be literals?
