System::ArrayPtr<uint8_t> memoryFont2 = System::IO::File::ReadAllBytes(u"customfonts\\CustomFont2.ttf");

System::SharedPtr<LoadOptions> loadOptions = System::MakeObject<LoadOptions>();
loadOptions->get_DocumentLevelFontSources()->set_FontFolders(System::MakeArray<System::String>({u"assets\\fonts", u"global\\fonts"}));
loadOptions->get_DocumentLevelFontSources()->set_MemoryFonts(System::MakeArray<System::ArrayPtr<uint8_t>>({memoryFont1, memoryFont2}));
