title: Reading Mail Reader Sampler response and asserting content in specific locale
body: <p>I am reading Gmail inbox using Jmeter Mail Reader Sampler. The email's subject line and body is in Japanese language.</p>
  <p>From the email response I have extracted the Subject line and some of the Body content and Now i want to assert those by putting the content in a dummy sampler as placeholder.</p>
  <p><strong>The challenge is the extracted result is appearing like question mark (<em>Subject: ????????</em>) in the response of the Dummy Sampler, which every-time fails the response assertion with matching or contains option.</strong> Debug Sampler also shows same question mark.</p>
  <p>I have also used the below property in the system properties, but no luck</p>
  <blockquote>
  <p>sampleresult.default.encoding=UTF-8</p>
  </blockquote>
  <p>I want to match the Subject line and other email content in Japanese language. Any suggestions?</p>
