When running a custom connector and selecting one of the roundtrips there are calls to the implementations of Connector.getContentInformation(ConnectorNode) and Connector.getContent(ConnectorNode)
In the method getContentInformation the passed ConnectorNodes ID returns the String with all special characters.
Right after, in the method getContent, the passed ConnectorNodes ID has replaced all special characters with Char-Unknown((char)65533).
When clicking on the picture of the Diagram to get a better view, both methods pass a Node with IDs that don’t display special characters.
The filesystem-connector throws an exception when passed a bpmn-diagram that has special characters in its name.
Furthermore it won’t display the image.
The file is displayed in the camunda-modeler without any issues.
