routed service returns responses with wrong encoding for Arabic letters

we have mocked services that are redireted with recoding option enabled.

now when the request gets a response from the routed URL there are fields that contains arabic letters.

the problem is the response gives back wrong letters.

i did add the encoding UTF-8 in the custom properties and added the following encoding option in the .vmoptions file with no luck:

-Dfile.encoding=UTF8
-Dsoapui.request.encoding=UTF-8
-Dsoapui.response.encoding=UTF-8

i also attached a screenshot showcasing the issue we're facing.

is there a way to fix that?
