How to check if given font family is a Composite font?

Question

We can enumerate over the fonts available on system using Fonts.SystemFontFamilies.

1. How can I distinguish between composite fonts and plain-font?
2. How can I get the FontFamilies used in a composite font?

I tried FontFamily.FamilyTypefaces, but it wasn't helpful.

Thanks

Try checking FontFamily.FamilyMaps, which should always be empty for physical fonts and non-empty for composite fonts.

var font1 = new FontFamily("Global User Interface");
var isComposite1 = font1.FamilyMaps.Any(); // True
var font2 = new FontFamily("Arial");
var isComposite2 = font2.FamilyMaps.Any(); // False
