title: Formatting Protobuf messages including non-ASCII strings
body: <p>When a protobuf message contains a string with non-ASCII characters, <code>message.toString()</code> returns something like</p>
  
  <pre><code>alarm {
    message: "\320\227\320\260\320\262\320\265\321\200\321\210\320\265\320\275\320\270\320\265 \321\201\320\262\321\217\320\267\320\270 \321\201 mzta1."
  }
  </code></pre>
  
  <p>I'd prefer to see the string including Cyrillic characters in logs. Is there a simple way to do this?</p>
