A math teacher I work with is having some trouble with PDF uploads displaying gibberish.


I don't think it's a PDF encoding issue because it opens fine locally and if she shares it as a Google upload. But, when it's uploaded to Canvas, the preview replaces all of the coefficients with "0" or "1". Here's a screenshot of the PDF in Canvas:


...and a screenshot of the same PDF opened in Google Drive:


Has anyone else seen this issue? I'm assuming it has something to do with the way is interpreting the PDF and not the document itself.


My recommendation, currently for the teacher, is to post these documents as a content page as links back to Drive. But, that's really a hassle because she then has to manage two different outlets. Any ideas?
