Unicode text rendering is cut mid way

[adirh3]

Describe the bug

Since recent changes (something from 26.11 to now), icon characters (Tested with Segoe MDL2 Assets) do not render properly.

To Reproduce

Easy way to reproduce with Control Catalog is to replace in ComboBox.xaml -

  <PathIcon x:Name="DropDownGlyph"
                      Grid.Column="1"
                      UseLayoutRounding="False"
                      IsHitTestVisible="False"
                      Height="12"
                      Width="12"
                      Margin="0,0,10,0"
                      HorizontalAlignment="Right"
                      VerticalAlignment="Center"
                      Foreground="{DynamicResource ComboBoxDropDownGlyphForeground}"
                      Data="M1939 486L2029 576L1024 1581L19 576L109 486L1024 1401L1939 486Z"/>

with

  <TextBlock x:Name="DropDownGlyph"
                      Grid.Column="1"
                      UseLayoutRounding="False"
                      IsHitTestVisible="False"
                      Height="12"
                      Width="12"
                      Margin="0,0,10,0"
                      HorizontalAlignment="Right"
                      VerticalAlignment="Center"
                      FontFamily="Segoe MDL2 Assets"
                      Foreground="{DynamicResource ComboBoxDropDownGlyphForeground}"
                      Text="&#xE70D;"/>

I can't see any issue here. You are explicitly limiting the width of TextBlock to 12 and the glyph is wider
