title: Why WSO2 Registry wouldn't store my chinese characters?
body: <p>I ran a WSO2 Registry server to maintain our configurations. It played its role perfectly, until one day I put some Chinese characters into resource content.
  I created a resource with 'Create Text Content', and Chinese characters into both 'Description' and 'Content' fields. When I opened this resource again, the 'Description' field remained Chinese, but the 'Content' text became a sequence of '?'(question marks, one Chinese character each).
  Why would this happen, and how to prevent it?</p>
