The problem has been fixed in versions 2023.1.3.326, 2024.1.1.193, 2025.1.1.72 by adding a mechanism in the installer (launched when installing or updating a WEBCON BPS version) to automatically update the attachment database, switch it to Unicode mode and change the text column types from varchar or text to nvarchar or ntext. The automatic update can take up to a few minutes for each attachment database.
