prevent Arabic characters from being entered in input field

I have a validation on an input field to prevent Arabic characters from being entered. The code works quite well except that you can’t add spaces.

https://jsfiddle.net/17b062wu/

jQuery(".no-arabic").on("input", function () {
        var inputValue = jQuery(this).val();
        var validChars = /^.*[u0600-u06FFs]+.*$/;
        if (validChars.test(inputValue)) 
        {
            alert('arabic text is not allowed');
            jQuery(this).val('');
        }
    });
