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;
        }
    }
}

Exporting document with invalid bookmarks throws System.Collections.Generic.KeyNotFoundException.

The issue is caused by an invalid bookmark having missing BookmarkRangeStart/BookmarkRangeEnd elements. As a workaround iterate through document elements and find the missing BookmarkRangeStart/BookmarkRangeEnd and insert the missing range.

Provide a way to change the Name of a FormField from the RadDocument.AcroForm.FormFields collection.

As a workaround, you could create a new instance of a FormField with the desired name, add the new field in the document and remove the old one. You can use the following approach:
   1) Create a new instance of FormField (with the desired name, passed in the constructor), which will play the role of a copy of a specific FormField
   2) Copy all properties from the original field (they all vary, depending on the concrete type of the FormField, for example CheckBoxField, etc.)
   3) Create a new widget for the new field, and copy all properties from the original field's widget into the new one.
   4) Remove the original field from the RadDocument.AcroForm.FormFields collection and add the new field.
   5) Remove the original widget from the corresponding page's annotation and add the new one.

Attached is a project demonstrating this approach for a CheckBoxField.

This API should provide a method for removing all fields and widgets in the document and draw the default widget appearance in place of the removed widgets.

WORKAROUND: Sample implementation for flattening form fields may be seen in the FlattenFormFields method from the attached demo project.

Support for exporting WMF (Windows Metafile) and EMF (Enhanced Metafile) images should be implemented.

Workaround: Convert the WMF images to PNG before exporting:
ImageSource imageSource = new ImageSource(new MemoryStream(this.ConvertWmfImageToPng(stream)));
document.Pages.AddPage().Content.AddImage(imageSource);
...
private byte[] ConvertWmfImageToPng(Stream wmfImageStream)
{
    byte[] pngBytes;
 
    using (MemoryStream pngImageStream = new MemoryStream())
    {
        System.Drawing.Image imageDrawing = System.Drawing.Image.FromStream(wmfImageStream);
        imageDrawing.Save(pngImageStream, System.Drawing.Imaging.ImageFormat.Png);
        pngBytes = pngImageStream.ToArray();
    }
 
    return pngBytes;
}

If HTML document is imported, and it contains image with invalid URL, then the image is imported with this URL in the document model. On subsequent export to Docx, the library tries to download the image data, which throws WebException. Instead, the image should be replaced with generic 'error' image.

Workaround: Manually test the image URL for correctness on HTML import, and replace the data:

        static void Main(string[] args)
        {
            HtmlFormatProvider htmlFormatProvider = new HtmlFormatProvider();
            htmlFormatProvider.ImportSettings.LoadFromUri += (sender, e) =>
            {
                if (!IsValid(e.Uri))
                {
                    e.SetData(File.ReadAllBytes("no-image.png"));
                }
            };
        }

        private static bool IsValid(string uri)
        {
            try
            {
                using (WebClient client = new WebClient())
                {
                    client.DownloadData(uri);
                }
            }
            catch (WebException)
            {
                return false;
            }

            return true;
        }

The same issue appears when exporting to PDF.
