Add support for ToUnicode CMap stream.

A side effect of not supporting it is the following: exporting PDF document which, for example, contains German umlauts, to plain text, leads to wrong characters in the resulting text.

As possible workaround, the PdfFormatProvider instance of RadPdfViewer can be used to import the document. For example:

FormatProviderSettings settings = new FormatProviderSettings(ReadingMode.OnDemand);
PdfFormatProvider pdfViewerFormatProvider = new PdfFormatProvider(stream, settings);
 
RadFixedDocument document = pdfViewerFormatProvider.Import();
 
TextFormatProvider textFormatProvider = new TextFormatProvider();
String text = textFormatProvider.Export(document);

This new API will not read/delete the existing PDF pages content and this would allow performance and memory efficient realization of the following scenarios: 

 - Merge PDF document pages from different PDF files.

 - Split PDF document pages to separate PDF files.

 - Append/Prepend PDF content to existing PDF pages.

Moreover, as this approach will not require reading/deleting existing PDF page content, it will not depend on complex PDF features and will depend only on the PDF file structure. This will allow processing of PDF documents which use less common PDF features which are currently not supported by the existing PdfProcessing API.

This is reproducible with specific PDF files which use custom Encoding for the fonts of the field widgets. 

WORKAROUND: Change the font of VariableContentWidgets before editing the field value. You should additionally call RecalculateContent() method of these widgets if the value of their corresponding fields is not edited. The following method may be used for changing the font of all existing widgets in the document:

private static void FixEncodingIssues(RadFixedDocument document)
{
    foreach(Annotation annotation in document.Annotations)
    {
        VariableContentWidget widget = annotation as VariableContentWidget;

        if(widget != null)
        {
            widget.TextProperties.Font = FontsRepository.Helvetica;
        }
    }
}

The CropBox is currently not supported by RadFixedPage class and is not preserved on an Import-Export scenario with PdfFormatProvider. CropBox is also not supported by PdfPageSource class and it is not preserved by using PdfStreamWriter as well. This property should be implemented in both scenarios.

The issue is reproducible only with nested tables - tables positioned inside some other table cell. When using simple tables the text is always wrapped and rendered correctly. This may be used as a workaround for scenarios which allow replacing nested tables with simple ones.
