How do I remove emoji code using JavaScript? I thought I had taken care of it using the code below, but I still have characters like

I know this post is a bit old, but I stumbled across this very problem at work and a colleague came up with an interesting idea. Basically instead of stripping emoji character only allow valid characters in. Consulting this ASCII table:

http://www.asciitable.com/

A function such as this could only keep legal characters (the range itself dependent on what you are after)

function (input) {
            var result = '';
            if (input.length == 0)
                return input;
            for (var indexOfInput = 0, lengthOfInput = input.length; indexOfInput < lengthOfInput; indexOfInput++) {
                var charAtSpecificIndex = input[indexOfInput].charCodeAt(0);
                if ((32 <= charAtSpecificIndex) && (charAtSpecificIndex <= 126)) {
                    result += input[indexOfInput];
                }
            }
            return result;
        };

This should preserve all numbers, letters and special characters of the Alphabet for a situation where you wish to preserve the English alphabet + number + special characters. Hope it helps someone :)
