BizTalk 2013 HL7 assembler replaces national characters with question marks

Question

When I try to produce a HL7 encoded message from through the HL7 assembler in BizTalk 2013 all national characters like å,ä,ö are replaced with a question mark.

I have promoted the property http://HL7Schemas.HeaderPropertySchema#MessageEncoding with the value 65001 but the output file is not UTF-8.

Does anyone have any experience from this?

Answer 1

I was creating the message parts in pipeline component instead of in an orchestration. What I had missed was setting the Charset property to "utf-8" on the new message parts.
