Are you using Chromebooks specifically?
If so, can I ask which barcode scanner(s) you're using which does work? The easiest solution may just be to buy a different scanner.
I did also email the manufacturer - let's see if they have a solution.

Alternatively (but probably less usefully), try it on https://w3c.github.io/uievents/tools/key-event-viewer.html
I'd guess it's the scanner though, I don't think those control characters are supposed to be sent.
