How String.fromCharCode function is used in html input fields with mobile keyboard

Question

I want to capture keyboard key codes and convert them into characters. I am using String.fromCharCodejavascript function but it only works with computer keyboard and not mobile keyboard. Any help would be greatly appreciated. $(".inputsmeter").keyup(function(e){letkey=e.which;letc=String.fromCharCode(key);alert(c);});

const inputElem = document.getElementById('input')
inputElem.addEventListener('input', (ev) => { 
  console.log(ev);
  alert(`e.data: ${ev.data}`);
});

This works as expected on my iOS Safari 15. Type a in the input and you will see the warning printed:

ev.data: a
