Your demo fails at the task hence the question. Example of QRs: https://stackoverflow.com/questions/37996101/storing-binary-data-in-qr-codes

Just did some tests using binary data. It is not working as expected. It is building a binary string in such a way that is read as unicode. Seems it uses TextEncoder internally, that mishandle binary data.

Just pushed up a PR to support this. You'd be able to create a QR code from gzip'd content or a protobuf encoded payload (our use case) or any other binary payload and scan it using this package.

It initially started as a patch file in our project but I figured it'd be worth it to share
