When the first symbol in the text string array is empty the text translation is not taken into account.

This leads to a letter misplacement (too far from each other or overlapping each other).

The rendering of the image is not fully parsed and the next attribute cannot be properly read. 

System.InvalidCastException: 'Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfArray' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfInt'.'

While all the pages and components of the control are rendered on the image, the content is completely missing from it. The issue is a regression caused by the migration of the model and its async rendering introduced in R3 2020.

Workaround: Fallback to the old rendering engine:

• Changing the default behavior:

 this.pdfViewer.DefaultImportSettings.UseOldRendering = true;

• Setting the property to the format provider used to show the document:

PdfImportSettings settings = PdfImportSettings.ReadOnDemand;
settings.UseOldRendering = true;

A rectangle is rendered as a solid rectangle instead of a rectangle with no fill.

When Windows11Theme is applied before the PdfViewer is initialized the CurrentPageTextBox is not loaded successfully.

Workaround: Set the ApplicationTheme after the InitializeComponent method:

public MainWindow()
{
	InitializeComponent();

	StyleManager.ApplicationTheme = new Windows11Theme();
}

A regression in Glyphs rendering:

The CurrentPageTextBox in the toolbar has stopped displaying in the latest version.

Workaround: 

<telerik:CurrentPageTextBox x:Name="PART_CurrentPageNumberTextBox" 
                            HorizontalContentAlignment="Center" 
                            Margin="2" Text="{Binding FixedDocumentViewer.CurrentPageNumber, Mode=TwoWay}"
                            VerticalContentAlignment="Center" Width="45" 
                            telerik:StyleManager.Theme="Office_Black"/>
