Umlauts changed in dataweave output

Question

I have special characters in my json response which are german umlauts (ä,ö,ü).

I have set the encoding to UTF-8 and this should work but the output from dataweave is Ã¼ and Ã¤ and Ã¶ and it is a com.mulesoft.weave.reader.ByteArraySeekableStream datatype.The input is a byte[].

How can I set my workflow up so the response shows the umlauts and not junk?

Dataweave Input Payload:

{
  "id": 1234567890
  "name": "prod123",
  "desc": "ü and ä and ö"
}

Dataweave Mapping:

%dw 1.0
%input payload application/json
%output application/json encoding="UTF-8"
---
{
    "status": 0,
    "desc": payload.desc
}

JSON Response:

{
  "status": 0,
  "desc": "Ã¼ and Ã¤ and Ã¶"
}

Are you sure you are reading or logging your JSON response using UTF-8 encoding? Maybe its properly encoded, but as your output is a Byte stream, if you are somehow decoding using another encoding (such as ASCII) it may seem an error. Also, are you sure the input payload is encoded as UTF-8? — Pierre B.
I have set the content type of the message to application/json; charset=UTF-8. I am also having problems with Chinese characters like 傳 too. — user3165854

Just remove the encoding property on output from your dataweave script and you should get proper output as expected. I tested in my local and it works fine. The reason it does not work with UTF-8 is because your input might be encoded with some other encoding.
