I have looked at the previous issues with text rendering when using print to PDF, and this suggests using Wolfram Cloud due to missing fonts. However, I have consist problems when using Wolfram Cloud. It seems that as soon as I use a non-alphabet character (including basic =,+,;), the print to PDF rendering does not match with the input, even if I then delete the characters.
I want to use the cloud for teaching, so want instructions I can give students that aren't "install Mathematica/go to a computer lab"
Input:
PDF:
I have tried Chrome, Safari, and Firefox, all up-to-date on Mac.
