Answer 1

Just googled and result

function displayunicode(e) {
  var unicode = e.keyCode ? e.keyCode : e.charCode;
  console.log(unicode);
}

<form>
  <input type="text" size="2" maxlength="1" onkeyup="displayunicode(event); this.select()" />
</form>

Answer 2

If you are looking for an online tool, https://keyjs.dev is probably the best option available:

• By default, it displays e.key, e.code, e.which and e.keyCode for the keydown event.

• If you need more than that, you can expand it and you will get a table with more properties for keydown, keypress and keyup.

• If you still need more than that, open DevTools and you will see all the keys you press are logged to the console in a table-like style. Just click the row you are interested in to expand it and see the whole event object.
