node:readline support reading non printable characters such as group separator

What is the problem this feature will solve?

When using a USB barcode reader on a TTY app that uses node:readline the group separator character \x1d is needed for GS1-128 barcodes. GS1-128 barcodes contain multiple elements defined by an Application Identifier (AI) that is a 2-4 digit code followed by value. Either a defined length is expected for the data or it looks for the group separator character for early termination of the value.

What is the feature you are proposing to solve the problem?

accept some or all non printable characters as inputs to readline

One of the following

1. add a flag to turn on that by default is disable to preserve existing implementations
2. add an option to explicitly define allowable non printable characters, defaults to an empty list
3. both a global flag and a list

What alternatives have you considered?

I've considered writing my own, seems like a bad idea for support and security. I may look into putting in a PR but I'm starting with a feature request.
I've considered rewriting the application into a non NodeJS application.
I've considered just replacing the TTY app with something more "modern" but there are external layers affecting this decision. This wouldn't allow copy/pasta of other characters which could be useful in some edge cases.

Commencez par examiner la gestion des entrées TTY de node:readline et la manière dont les caractères non imprimables sont actuellement traités. L’issue propose soit un flag global, soit une allowlist, soit les deux ; il faudrait donc d’abord trancher ce choix de conception. Le travail est considéré comme terminé lorsque le séparateur de groupes peut être lu sans modifier le comportement existant de readline, avec une couverture pour l’option choisie.
