iPhone Camera App adds unexpected %20 encoding #72

I found an annoying issue with the Base45 encoding. Scanned with the iPhone Camera App and selecting the unusable data to copy copies the data, but encodes all Spaces as %20 for some reason. I checked the actual bytes in the QR Code and they are spaces.

We are aware this issue and other issues with HC1 encoding. Many camera apps assume that scanned payloads are URIs, and HC1 payload is not.
