Prior to spoova 1.5, ajax urls do not support the use of special characters. A sample of this is explained below.
<script>
let xhttp, url, params;
xhttp = new XMLHttpRequest();
url = "some-url";
params = window.location.search;
xhttp.onreadystatechange = function(){
}
xhttp.open("GET", url + params, true);
xhttp.setHeaders('X-Requested-With', 'xmlHttpRequest');
xhttp.send();
</script>
"_" character. In version 1.5.0, this bug has been resolved and ajax urls can now receive request paramaters from urls as long as the url is of a valid structure.
