title: Does pandas to_json have an encoding parameter?
body: <p>I want to make a dataframe a json object.</p>
  
  <p>For example, </p>
  
  <pre><code>function f():
      ...
      ...
      ...
      return dataframe.to_json(orient='records',force_ascii=False)
  </code></pre>
  
  <p>but to_json does not have encoding paramter like <code>to_csv</code></p>
  
  <p>How do I encode with utf-8 in the case of <code>to_json</code>?</p>
  
  <p>thank you for reading.</p>
