title: Dialog flow Agent Query with input String in Japanese / Arabic
body: <p>I am using dialog flow V1 Apis to query the agent. There is a scenario where the input query string is not english. The language I want to send in is a Japanese / Arabic string </p>
  
  <p><strong>Sample Request</strong></p>
  
  <p>endpoint = "<a href="https://api.dialogflow.com/v1/query?v=20150910" rel="nofollow noreferrer">https://api.dialogflow.com/v1/query?v=20150910</a>";</p>
  
  <p>JSON Data</p>
  
  <pre><code>{
      "originalRequest": {
          "data": {
              "incomingMessage": "朝食時間は何ですか？"
          }
      },
      "lang": "ja",
      "query": "朝食時間は何ですか？",
      "sessionId": "###########"
  }
  </code></pre>
  
  <p>In dialog flow agent, it is received as </p>
  
  <pre><code>æé£æéã¯ä½ã§ããï¼
  </code></pre>
  
  <p>How do i pass it to the query endpoint so that the dialog flow agent can read the input query in the language i send. </p>
  
  <p>I am also aware that Dialog flow will not Arabic. I tried with a Japanese string as well and ended up with same kind of results. I tried changing the "lang" property to "ja", still it didn't work. Should I encode the "query" property in a certain format?</p>
