Please try to use FontImageSource to show the font icon, is that working?

<Image BackgroundColor="#D1D1D1"> <Image.Source> <FontImageSource Glyph="" FontFamily="{OnPlatform iOS=FINPERC, Android=FINPERC.ttf#}" Size="44" /> </Image.Source> </Image>

And you can download ttf file to make a test from offical MAUI demo with this Fonts in .NET MAUI - .NET MAUI | Microsoft Learn code. If it is working, it is related to the ttf file, please use other tools to make ttf file.
