* Operators: `<=` to `≤`, `>=` to `≥`, `!=` to `≠`.

1. Typography:

* Dashes: ` -- `, ` --- `.
* Ellipsis: `...` to `…`

1. Quotes:

* Primary quotes (english): `'Foo bar'` to `‘Foo bar’`
* Primary quotes (english): `'Foo bar'` to `‘Foo bar’`
* Secondary quotes (english): `"Foo bar's"` to `“Foo bar's”`

### Testing

* Check if the transformation works. Note that some might need a space to trigger (dashes).
* Undo a text transformation and type - it should not re-transform it.
* Change selection - the not transformed elements should stay.
* Change selection - the not transformed elements should stay.
