Have you confirmed that these characters do have UPPER CASE variations, as doing this would result in the systems returning a Square Character as your request is invalid. i.e. what is the UPPER CASE alt code for alt159

FOr validation purposes, you could apply an onblur event or onkeyup, which would perform a Replace on a range on Alt Codes in the Target Value. Meaning that when you come to perform the toUpperCase method, no character is there that you are unprepared for. A lit of these ranges can be found here

And also here you can adapt the return values in the toUpper() function to what you need:

<script>


function toUpper(theStr){
  return theStr.replace(/[a-z]/g,function(p){return p.toUpperCase()});
}


alert(toUpper("Zvonko"));
</script>
