This is expected behavior, all. At the core of the regex match is the data that we receive from a [JavaScript KeyboardEvent](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent) because this executes in the scope of the browser. We’re assembling a character sequence to match against from an input source (your barcode scanner) that creates KeyboardEvents. A “new line” character shows up as a key press for the “Enter” key.

[https://keycode.info/](https://keycode.info/) is a pretty decent way to test what KeyboardEvent data your sequence would produce. It tests a key at a time, but knowing what your sequence looks like, you could type it out on your keyboard to generate the KeyboardEvent and observe the `event.key` value in the tool.
