I discovered the same thing when I was writing a tool the transmit data to a radio-free (no wifi or Bluetooth) airgapped computer and created a de-facto standard called "qrint". The comment in this file has enough text for a blog post.

• QRGenJS

  Unofficial fork of nayuki/QR-Code-generator

  

I built an open source tool to specifically work on this problem: https://convert.zamicol.com

We know only two open source JS projects that even support alphanumeric, Nayuki and Paul’s. https://github.com/Cyphrme/QRGenJS. We have it hosted here: https://cyphr.me/qrgen

I’ve also done a lot of work on this problem: https://image-ppubs.uspto.gov/dirsearch-public/print/downloa...

Also, regarding alphanumeric, RFC 3986 states that:

> An implementation should accept uppercase letters as equivalent to lowercase in scheme names (e.g., allow “HTTP” as well as “http”)
