MacOS Unicode troubleshooting

My MathPad just arrived today. Looks and feels great, congrats on the successful project!

I am on a Mac (M3 MacBook Pro, Tahoe 26.1) and so far I haven't been able to get the plaintext Unicode typing to work. LaTeX mode works fine so the keyboard is certainly functional.

I followed the manual and troubleshooting info.

1. MathPad Service is installed and running. Used current 1.0.0 DMG. Confirmed with 'ps ax | grep -i math'
2. Accessibility permission is granted, and on state persists when reopening Privacy & Security > Accessibility.
3. I updated the firmware to 1.2.0. Original was 1.1.0. Current debug output is below.
4. When the OS popped up the Keyboard Support Assistant on initial connection, I hit Quit. This has been the suggested action for other custom keyboards but I wonder if it is a factor here.

I tried plaintext mode in the Getting Started browser fields, TextEdit, and Obsidian with no output. I also tried Microsoft equation mode inside an Office equation field, same result.

Appreciate any help with ideas to get it working.

Hi apirkle!

Sorry to hear the plaintext mode is not working. It sounds like you followed the instructions correctly and the Mathpad is certainly alive, so I have to wonder what could be the problem.

I am able to replicate this bug on my side, and I am working on a fix.

Excellent. I downloaded the new release and Unicode works perfectly now. Thank you!

I'll reiterate how impressed I remain with this project. After posting the issue here I started delving into the source code. Found the unicode decoding bug and started attempting a fix, had thoughts of polishing it up this morning and submitting a PR, and I check back here to find that you've got a fixed release already out the door. Bravo.

Happy to hear it solved your problem! And thank you very much for posting about the issue here. Otherwise I would not have been aware of it.

Enjoy your Mathpad!
