Different types of barcodes (aka barcode methodologies) can encode different types of data. Some barcode methodologies can only read digits, some can read upper-case ascii text and digits. A full ascii character set is the most that you will get from most barcode methodologies.

QR Codes are the exception to the rule -- they can encode kilobytes worth of data, and it can be binary.

Barcode readers that read barcodes and send their data as if it were keyboard data are known as 'keyboard wedges' -- a quick google search for qr code keybaord wedge barcode scanner gave me this:https://www.amazon.com/NADAMOO-Wireless-Charging-Transmission-Rechargeable/dp/B07MH1X3WT/ref=sr_1_18?keywords=keyboard+wedge+barcode+scanner&qid=1557345202&refinements=p_n_condition-type%3A6461716011&s=gateway&sr=8-18 -- so finding the keysym for F11 and QR encoding that with a newline might do the job, reading from that barcode scanner.

The other option, mentioned several times in this thread, is to have the barcode scanner trigger a script which will send a keyboard event. This is possible, but I suspect that you'll end up running into the issues mentioned here: https://stackoverflow.com/questions/16714928/sending-keystrokes-to-a-x-window#16940275
... namely that many programs will reject keyboard input unless they have keyboard focus.

Finally, it's worth asking whether or not there's a different way to approach the problem -- can the F11 key be remapped within the program that you're trying to send data to? Maybe there's an API available that can trigger the same event? Perhaps the answer is to Duct tape a Keyboard someplace where the F11 key is in easy reach?
