Autocomplete not working on Android

[Ikrk]

Hello Carlos,
thanks for the good work.

I have just found out that the script does not work on Android (my phone has Android 8.0 and Chromium 86.0.4240.110).
The reason seems to be a Chromium bug where the keyCode of the keyUp event is not properly recognized and it is always 0 or 229. Therefore the condition if (/[a-zA-Z0-9-_ ]/.test(char) || key === 8) is never satisfied.

I have used a simple workaround and replaced this condition with something like:
if(self._prevInputValue != self._input.value && validInput(self._input.value))
and it works just fine. I am not a JS guy so there might be a more elegant way.

Regards,
Ikrk
