Webpages show garbage symbols for some words (Ubuntu 18.04)
I'm running Firefox 83.0-2 on a fresh install of Ubuntu 18.04 on a Dell Precision 7550 laptop, and many webpages have words that look like they are not decoded properly (images below). Everything looks fine when using Chrome. Can anyone think what the issue is?
For the attached Wikipedia page, the pattern looks like it's specific to italicized hyperlinks. I also see it in other places, e.g. any comments in a Python Juypter notebook.
Any advice would be great.
