Below java script function will work fine, you can add number as well.

function myFunction() {
  var str = "xq234"; 
  var allowChars = "^[a-zA-ZÀ-ÿ]+$";
  var res = str.match(allowChars);
  if(!str.match(allowChars)){
    res="true";
  }
  else {
    res="false";
  }
  document.getElementById("demo").innerHTML = res;`enter code here`
