From what I understand about QR codes and custom protocol handlers,
the scanned code should be something like (contrived):
pem://<cert>
or:
csr://<cert request>
The "pem://" or "csr://" part allows the camera software to invoke the
proper protocol handler, like "https://"; does for a QR-encoded url.
What are you trying to do with the request once it is decoded?
