Safari Helvetica font issues - Question marks
Since I upgraded to Big Sur, Safari (and Apple Mail) is having issues discplaying some fonts correctly on some websites. For instance, Helvetica is displayed as loads of questions marks.
What I did so far:
- Cleared the font cache via Terminal
- Cleared the font cache by booting in safe mode
- I'm using Extensis Suitcase to manage my third party fonts, but even when I don't have Suitcase launched, the issue remains.
- In Font book, I checked all the fonts, no issue found.
- In Font Book, I cannot deactivate Helvetica, because in Big Sur the system fonts cannot be altered.
These question marks appear only in Safari, not in any other browser, and also only when I'm logged in as normal user. When logged in on my admin account, the fonts are shown correctly in Safari.
Any ideas how to fix this? Thank you for all your help!
