The Nonbreaking space is exported as a Unicode character instead of the appropriate Control word.

Actual: "\n160?"

Expected: "\~"

 An incorrect file is produced when merging a stream more than 40 times.

Workaround: A possible workaround could be to merge up to 40 times in one file, then continue merging in a new one, and finally merge the newly generated documents.

According to the RTF specification: The valid values for the "\ls" index are from 1 to 2000.

They are currently exported from zero or "\ls0".

When the table width is set to fixed with the value of zero:

<w:tblW w:w="0" w:type="dxa"/>

Add full support of the font-weight CSS property. The defined values are: normal, bold, bolder, lighter, 100, 200, 300, 400, 500, 600, 700, 800, 900. Currently bold and normal are supported.

Make it possible to import HTML file with an external style sheet, without the need to handle the LoadStyleSheetFromUri event in HtmlImportSettings. If the URL is correct the data can be internally downloaded.

Absolute positioning of images, defined in the class stylesheet, is not respected.

When exporting to a PDF file, a document with a header containing a watermark, set by a shape, the rest of the header content is skipped and the header is exported with default margin values.

A possible workaround could be to set the watermark as an image.

This element specifies that an absolute position tab character shall be placed at the current location in the run content.

The missing feature leads to this unwanted behavior:

• When there is content control, which generates content on interaction, and it has some custom run properties set to it, they are lost when the user modifies it.

As a workaround, you need to apply a custom style (with the desired run properties) and apply it to the content control.

When a watermark needs more space than the available on the page, it should be resized. At this point, part of its content can be cut off as it falls outside of the page bounds.

Workaround: Decrease the size of the watermark prior to exporting it to PDF:

foreach (var section in this.document.Sections)
{
    Header header = section.Headers.Default;
    if (header != null)
    {
        foreach (Watermark watermark in header.Watermarks)
        {
            if (watermark.TextSettings != null && watermark.TextSettings.Width > section.PageSize.Width)
            {
                watermark.TextSettings.Width = section.PageSize.Width;
            }
        }
    }
}
