// Font families come from a collection; later families cover what the first lacks.
FontCollection fonts = new();
fonts.AddFile(System.IO.Path.Combine(folder, "NotoSans-Regular.ttf"));
fonts.AddFile(System.IO.Path.Combine(folder, "NotoSansArabic-Regular.ttf"));
fonts.TryGetFamily("Noto Sans", out FontFamily latin);
fonts.TryGetFamily("Noto Sans Arabic", out FontFamily arabic);

// Styles nest: the inner span keeps the outer one's size and adds a color and an underline.

    .Append("\u0633\u0644\u0627\u0645 ")

    .Append("in Arabic")
    .Pop()
