How to check the response encoding of a wcf service

Question

We delivered a WCF service with a custom binding which should return utf8.

Now the caller of the services says the service does not return utf8 encoded content.

We checked the header and that is ok(it says utf8) but the question is: how can I check if the response message itself is utf-8 encoded?

(I use soap ui to call the service, but other tools are ok too)

Answer 1

you can use any network tools like wireshark or fiddler...but your encoding must be visible in the config- check with wcf config editor tool
