When importing a document containing text fragment with a wrong Type3 font set the glyph cannot be obtained from the font and an exception is thrown: System.InvalidOperationException: 'Cannot create glyph with charcode: <<>>'

When the Font`s Widths array contains entries defined as Indirect references an exception is thrown: System.ArgumentException: 'The IndirectReference type cannot be converted to a real numeric value.'

According to the Pdf Specification: The glyph widths are measured in units in which 1000 units corresponds to 1 unit in text space.

When Bold and Italic properties are set in the TrueType font file`s OS/2 table they are not respected and the OpenTypeFontSource`s Bold and Italic properties are not correct.

A small line is drawn in the top left corner when converting a paragraph with a shading color to a PDF

Workaround: 

var table = header.Blocks.AddTable();
table.PreferredWidth = new TableWidthUnit(TableWidthUnitType.Percent, 100);
var row = table.Rows.AddTableRow();
var cell = row.Cells.AddTableCell();
cell.Shading.BackgroundColor = new ThemableColor(Colors.Red);

var head = new Run(doc);
head.Text = "Test";
var paragraph = cell.Blocks.AddParagraph();
paragraph.TextAlignment = Telerik.Windows.Documents.Flow.Model.Styles.Alignment.Center;
paragraph.Inlines.Add(head);

When invoking the FontsRepository.TryCreateFont() method to create Font from an installed TrueType font with font properties set (FontStyles.Italic, FontWeights.Bold) the name of the created font is not correct.

FontBase font;
bool isRegistered = FontsRepository.TryCreateFont(new FontFamily("Helvetica"), FontStyles.Italic, FontWeights.Bold, out font);

Expected:<Helvetica-BoldOblique>
Actual:<Helvetica,Italic>

Wrong calculations of new lines and white spaces between characters due to a wrong calculated character`s BoundingRect.

This results in missing whitespaces and/or characters split between lines.

According to the Pdf Specification: A given object number must not have an entry in more than one subsection within a single section.

The object on line 7 has object number 2, the same as of object on line 5.

Currently, when registering *.pfb font file with FontsRepository.RegisterFont method an exception is thrown during the font creation. 

WORKAROUND:  The font file may be converted to TTF format (*.ttf) which is successfully registered.

Some Shading elements are not property imported which leads to unexpected drawings on the exported (previewed in the PdfViewer) document.

When importing a document with a missing state separator (e.g. linefeed) in the object stream (ObjStm) an exception is thrown: System.InvalidCastException: 'Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfDictionary' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfInt'.'

А possible workaround could be handling the exceptions: Handling Exceptions.

When importing a document containing a CIDFont with default width (DW) set as PdfReal (double) an exception is thrown: System.InvalidCastException: 'Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfReal' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfInt'.'

According to the PDF Specification: DW - integer - (Optional) The default width for glyphs in the CIDFont. Default value: 1000.
