When converted both are seen properly on Mac OS Catalina, however within the new release of Mac OS Big Sur the filled one (along with several other examples in my icon set) render as completely filled. Here's an example of it right from the online testing library.

Now, to be clear compiling the icon set on Mac OS Big Sur works fine when viewed in Catalina, it seems that however the font is being generated Big Sur is having issues with how to display it properly. It's basically as if you'd removed the fill-rule on the path. I've dug through previous issues and am not seeing anything similar even though others have had different rendering issues. Does anyone have any ideas?

I'd like to add that this isn't just in Big Sur, it's also icons displaying on iOS 14 from what I can tell.

Similar issue to #62

After further research this issue certainly seems to be related to the SVG fill rules. It seems for vector objects that worked fine previously are more sensitive to these issues when viewed in Big Sur and iOS 14. For those designing SVGs in Figma (like myself) you can use the Fill Rule Editor plugin to adjust the fill rule and direction.
