Release R1 2023
When a ToUnicode CMap is defined for Simple Font (TrueType or Type1 font) which maps font character codes to two or more Unicode character values, the extracted text should contain the whole set of characters defined in the mappings. The current implementation of RadPdfViewer takes the first character specified in the ToUnicode mapping which leads to missing characters.

When making changes to Form fields then flattening them and invoking the viewer`s Save method an exception is thrown: System.Collections.Generic.KeyNotFoundException: 'The given key was not present in the dictionary.'

Code to reproduce the issue:

this.pdfViewer.Document.AcroForm.FlattenFormFields();

using (Stream output = File.OpenWrite("Exported.pdf"))
{
	this.pdfViewer.Save(output);
}
Workaround: Export the document using the PdfFormatProvider:
this.pdfViewer.Document.AcroForm.FlattenFormFields();

using (Stream output = File.OpenWrite("Exported.pdf"))
{
	PdfFormatProvider provider = new PdfFormatProvider();
	provider.Export(this.pdfViewer.Document, output);
}

	InitializeComponent();

}
