Installing fonts with the Affinity suite is extremely frustrating. Whether it’s through the Affinity apps, or through a third party font installer, or through Creative Cloud, it’s almost impossible to get them to work. If they show up at all in the font list, there’s a good chance they will be displayed as generic Chinese characters, and I’ll have to test each one to see what font it actually is. Then the next time the app is open, there’s a good chance the fonts will be gone, even if they show up in the installed fonts in the Affinity settings. It’s been more than six months since this issue appeared, I would think this would be a pretty big priority, but it’s still broken.
