在将 Segoe MDL2 资产的字符转换为字符串后显示字符的错误

Question

我正在使用 xaml 通用项目，在代码隐藏中转换为字符串后，无法显示 Segoe MDL2 Assets 字体的某些字符。请查看图片和任何有想法的人如何解决这个问题：

Xaml:

<converters:MyTypeConv x:Key="myTypeConv" />

<dSrc:clsLstElem x:Key="lstCmdAnsw">
        <dSrc:clsElem iAuto="0" />
        <dSrc:clsElem iAuto="1" />
        <dSrc:clsElem iAuto="2" />
</dSrc:clsLstElem>

Xaml 用法：

 <Border CornerRadius="5" BorderBrush="Black" BorderThickness="1">
    <ItemsControl ItemsSource="{StaticResource lstCmdAnsw}">
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <ItemsWrapGrid Orientation="Horizontal"/>
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <Button
                 Content="{Binding iAuto, Mode=OneWay, Converter={StaticResource myTypeConv}}" 
                 FontFamily="Segoe MDL2 Assets" 
                 FontSize="{ThemeResource ContentControlFontSize}" />
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</Border>

后面的代码：

     public class MyTypeConv : Windows.UI.Xaml.Data.IValueConverter
     {
        public object Convert(object value, Type targetType,
                                  object parameter, string language)
        {
                    string s = string.Empty;
                    if (value != null)
                    {
                        switch ((int)value)
                        {
                            case 0:
                                s = "\uE81D";
                                break;
                            case 1:
                                s = "\uE927;";
                                break;
                            case 2:
                                s = "\uE916;;";
                                break;
                        }
                    }
                    return s;
         }
}

Answer 1

删除结尾的分号，即替换

s = "\uE927;";
s = "\uE916;;";

来自

s = "\uE927";
s = "\uE916";
