Is it possible that this is related to #16604?

I think that direct support for WOFF fonts in native Android apps is not provided.

What I meant: the original post mentions Material Symbols and links to a specific font file, which are variable fonts. Currently MAUI does not support variable fonts.

In order to use those fonts, currently they have to be converted to static fonts with given settings for e.g. weight and fill (explained in #16604). That issue was actually reported to triggered by the lack of built-in support for using Material Symbols.

@kubaflo Can you please check whether this is a duplicate of the earlier #16604?
