When loading some PDF documents with German culture, part of the text got missing.
Workaround: set English culture before loading the document
Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");
When importing a document with button field with missing type, an error occurs.

Workaround: Handle the exception: https://docs.telerik.com/devtools/document-processing/libraries/radpdfprocessing/features/handling-document-exceptions
RadPdfProcessing currently supports interactive forms whose data is defined directly in the document. To preserve them when importing and exporting documents, add support for import-export interactive forms based on the Adobe XML Forms Architecture (XFA).
From PDF 2.0 the XFA forms are depreciated.
Following the steps:
1. Create two PDF documents that contain form fields where the name contain a period, e.g. "person1.name".
2. Merge the two documents: https://docs.telerik.com/devtools/document-processing/libraries/radpdfprocessing/model/interactive-forms/form-fields/formfields#merging-documents-with-form-fields
PdfStreamWriter: "InvalidOperationException: 'isContentReleased'" is thrown when creating a multi-page document with an umlaut on the last page.
Workaround - Explicitly set the block font:block.TextProperties.Font = FontsRepository.Courier;
Support for FileAttachment annotations.
A file attachment annotation contains a reference to a file, which typically is embedded in the PDF file.
