  • Fixes that typing an emoji on iOS could result in a broken U+F44F: INVALID CHARACTER
  • Adds support for determining keypress event input from the event.key property when available and support for handling event.keyCodes > 65535

The root of the problem was the use of String.fromCharCode for handling event.keyCode. When you type a "πŸ‘πŸ»", for example, on iOS Safari you get a keypress event (TIL!) with an event.keyCode of 128079. The maximum value String.fromCharCode accepts is 65535 (216 - 1), and passing a larger value results in an incorrect string value:

> string = String.fromCharCode(128079)

> string.length

> string.codePointAt(0)

> string.codePointAt(0).toString(16)
