Output Encoding issue in mule esb - mule

Question

I have used to do create XML using "Transform Message" Node in Mule ESB.
%dw 1.0
%output application/xml
item: {
name: payload."profile_name",
id: payload."profile_Id"
}
This shown a preview of output xml as
<?xml version='1.0' encoding='windows-1252'?>
<item>
<name>
<profile_name>????</profile_name>
</name>
<id>
<profile_Id>1</profile_Id>
</id>
</item>
This resulted encoding as 'windows-1252' how can i change encoding as 'UTF-8' in my outpout xml ?

Answer 1

Go to your Anypoint Studio folder.
Edit AnypointStudio.ini
Add:
-Dfile.encoding=UTF-8
Restart

Answer 2

Easy, define encoding in the output line:
%dw 1.0
%output application/xml encoding="utf-8"
---
name: payload.name?
the result:
<?xml version='1.0' encoding='utf-8'?>
<name>false</name>

Answer 3

For dataweave in runtime above 3.8.4 I implemented this solution:
set output as variable:
Output FlowVar - fv_itemName_xml
inside of Transform Message:
'%output application/xml writeDeclaration=false
item: { name: payload."profile_name", id: payload."profile_Id" }
and output will be:
<item>
<name>
<profile_name>????</profile_name>
</name>
<id>
<profile_Id>1</profile_Id>
</id>
</item>
Then define a variable as below:
Name: fv_outputName_xml
Value: #[flowVars.fv_itemName_xml]
Encoding: ISO 10646/Unicode(UTF-8)
Mime type: application/xml
And you have better control of Encoding and Mime type.
In my case I was need to feed that into Stored Procedure and without this workarround constantly receiving error:
System.Data.SqlClient.SqlException (0x80131904): XML parsing: line 1,
character 39, unable to switch the encoding
