As you can see the Üüÿê is printed as ▄³ Û. The characters Üüÿê are also in the POST body of SOAP UI. But they're printed as ???. I have an implemantation which does not use RESTlet where this works. So the settings in SOAP UI are not the problem. (The POST body is in Application/JSON btw.)
How can I extract the unicode chars Üüÿê from the POST body without getting them as ??? ?
