code128 | Trivial Code 128 barcode encoder | Barcode Processing library

In my barcode contains a Norwegian character (Ålesund). But while scanning it on the Zebra device I am not getting the letter (Å) instead I am getting something like this (�lesund).

The configuration that I am following the app is,

I'm using Barcode4J library to generate barcodes. I am returned a BufferedImage that I can display as an ImageIcon on a JLabel and save to a file but I can't for the life of me print it to a printer, the drawString and drawRect work as expected but the image is blank. I've posted some code below; I don't know how to make it a SSCCE of this but if anyone can point me in any direction I would be most grateful.

In the past, we've used ZPL to create Code39 barcodes with a TAB character encoded in the middle using something similar to the following:

I am using the barcode_widget to generate both barcode and 2d QR code. But I also need to print and save the codes.

My Current code for generating bar code and qr code is as below:

I am trying to subclass a fabricjs Image for a barcode field.

It's the first time I've used library. Hence the question I asked about the library: link

Add a barcode to my label? On the Website it says for a label it goes with it:

So, I want to display a string as Barcode. I want to use Code128 Auto. And I dont want to use nuggets. How Can I do that? At the end I just want to have an TextBlock in WPF with the String of BarCode in it.

EDIT

So I already have an Font of Code128 in my Textblock in WPF. But my Problem is, that I cant scann the barcode font with an Barcode scanner.

So I have an TextBox and for that TextBox im using the Font from Code128 to get the Barcode look. But with that i cant scann this Barcode. How I need to change the TextBox, so I can scan the barcode with an Scanner?

So I realize there are several questions about this but I feel like I've reviewed them all and still haven't figured out what I did wrong or different. I call this class from a function that I know happens after viewDidLoad. What I am trying to do is be able to take a video stream from a given AVCaptureDevice or camera id and pass this into a WebView as a series of evaluateJavascript calls, I may need to optimize this later but I'm having trouble just getting captureOutput to be called. Certainly, I don't need a preview to be able to capture the output do it? I've confirmed the permissions are correct and the code reaches the point where the sample buffer delegate is being set on the capture session. Any ideas?
