在Xamarin.Forms中，使用Fontello字体中的字形非常简单：
1.下载字体，例如smiley.ttf。
1.以Embedded Resource

的形式添加到项目
1.导出字体：
[assembly: ExportFont("smiley.ttf", Alias = "smiley")]
1.将xaml中的标志符号用于Text属性：

<StackLayout BackgroundColor="#eeeeee">
    <!--Uses glyph #E800 from smiley.ttf-->
    <Button BorderColor="Aqua"
            BackgroundColor="Yellow"
            BorderWidth="5"
            CornerRadius="10"
            FontSize="150"
            FontFamily="smiley"
            Text="&#xE800;"
            TextColor="Black"
            VerticalOptions="CenterAndExpand"
            HorizontalOptions="CenterAndExpand"
            HeightRequest="200"
            WidthRequest="200" />
</StackLayout>

然后一眨眼的功夫：

我想在Winforms中做同样的事情。下面是我尝试的：

public MainForm()
{
    InitializeComponent();

    // For the sake of simplicity, the TTF is copied to output directory...
    var path = Path.Combine(Path.GetDirectoryName(Assembly.GetEntryAssembly().Location), "Fonts", "smiley.ttf");
    // ... and loaded here.
    privateFontCollection.AddFontFile(path);

    var fontFamily = privateFontCollection.Families[0];
    Debug.Assert(fontFamily.Name == "smiley", "Expecting 'smiley' is the font family name");

    button1.Font = new Font(fontFamily, 12F);
    button1.UseCompatibleTextRendering = true;

    // Shows 'A'
    // button1.Text = "A";

    // Shows nothing.
    button1.Text = "\u0E00";
}

PrivateFontCollection privateFontCollection = new PrivateFontCollection();

这样的事情甚至可能吗？我尝试了button1.UseCompatibleTextRendering = true和Application.SetCompatibleTextRenderingDefault(true)的各种设置都没有成功。
