When opened in Adobe Reader it says that the file "claims compliance". However, when verifying the compliance with some validation tools there seem to be some issues mainly related but not limited to fonts.

When merging, only the widgets are copied but not their fields. This can lead to ArgumentNullException when exporting the document. Implement copying the fields and consider cases which include collision of names of the fields.

Workaround:
Repair the generated document using the following code:
foreach (Widget widget in this.pdfDocument.Annotations.Where(annot => annot.Type == AnnotationType.Widget))
{
    if (!this.pdfDocument.AcroForm.FormFields.Contains(widget.Field.Name))
    {
        this.pdfDocument.AcroForm.FormFields.Add(widget.Field);
    }
}
In case of Name collision, you can use the attached project or the attached project to the following feedback item to rename the duplicate fields: Provide a way to rename FormFields.

Release 2024.1.305 (2024 Q1)
For example exporting the text "\uD83D\uDE0A" with "Segoe UI Symbol" font family should export a single smiling face. Instead the characters are skipped during the export as PdfProcessing is trying to export them as separate char values ("\uD83D" and "\uDE0A") and the font does not contain glyphs corresponding to these char codes.

Release R1 2023 SP1
The current implementation relies on valid cross-reference offsets in the PDF documents so that PDF objects are easily found and parsed. However, we may implement a mechanism for importing documents with invalid offsets for the objects inside the table.

When creating a GradientStop, an alpha channel of the color could be applied. However, this setting is not respected it the result document and the gradient is with full opacity.

Steps to reproduce:
1. Create a gradient with an alpha channel:

RadFixedDocument document = new RadFixedDocument();
RadFixedPage page = document.Pages.AddPage();
FixedContentEditor containerEditor = new FixedContentEditor(page);

LinearGradient linearGradient = new LinearGradient(new Point(0, 0), new Point(30, 30));
linearGradient.GradientStops.Add(new GradientStop(new RgbColor(10, 0, 207, 0), 0));
linearGradient.GradientStops.Add(new GradientStop(new RgbColor(10, 0, 102, 204), 1));

containerEditor.GraphicProperties.FillColor = linearGradient;
containerEditor.DrawRectangle(new Rect(10, 10, 48, 29));

2. Export the document to PDF

Observed: The alpha channel is not respected and the gradient is with full opacity

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 issue may be reproduced by opening the attached PDF in Adobe Reader. Although the viewer initially shows the characters correctly, when you start typing in the TextBox, the umlaut/diacritics characters get corrupted. In other PDF viewers, the umlaut characters are handled correctly, so the issue seems to related to concrete Adobe Reader encoding handling implementation. The diacritic characters are handled incorrectly in other viewers as well (e.g. Chrome).
