Release R3 2019
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 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.

By specification, the document AcroForm contains fields with no parents. However, some documents may have child fields in the AcroForm. This leads to ArgumentException when importing the child and parent fields - 'An item with the same key has already been added.' since the child field is added twice.

Some field values are initially not visible when opening file exported with RadPdfProcessing in Adobe Reader. The field value becomes visible once you click (focus) the field in Adobe Reader. The setting which causes this UI rendering issue may be found in "Edit" -> "Preferences" -> "Forms" -> "Highlight Color" -> "Show border hover color for fields". On the attached screenshots you may compare the rendering result when this setting is On and when it is Off.

Fix available in LIB Version 2017.2.710.
