we figured out that the data hub seems to have a problem with special characters (i.e. ä,ö,ü). Within SAP Integration we have classification attributes that consists of these characters. The canonical items do have '?' instead of the special characters. With debugging we found out that the special characters arrive correctly within the datahub idoc input channel.
Does the data hub fully support UTF-8 characters? Is this a bug?
Kind regards, Stephan
