I am trying to replace Japanese half-width characters to full-width
characters.
ｳ -> ウ
So whenever a user types in half width, we have to convert to full width
automatically.
Obvious solution would be to design a directive to change the ngModel on
keypress. But we have a huge codebase and I was thinking maybe with
`@Hostlistener` would be able to change the value.
```
@HostListener('document:keyup', ['$event']) onKeydownHandler(event) {
if (event.target.hasAttribute('type')
&& event.target.attributes['type'].value === 'text') {
event.target.value = this.changeToFullWidth(event, event.target.value);
}
}
```
However with this `[(ngModel)]` is always one character behind and I know
this is because I am touching the HTML element directly.
Is there a way to do this ? Or will I have to go harder approach of adding
directive to each input tag in whole project?
