title: How to send "special characters" with Python Actions Send_keys?
body: <p>I am making a code in Python 3.7 for testing an application in Appium.</p>
  
  <p>I am trying to send a text in an input field of an application. The text is in French with special characters (é, è, à, etc.).</p>
  
  <p>My code managed to type character by character, one by one, but when it arrives to a special character with accent "é", it bugs! Here is error message:</p>
  
  <pre><code>Encountered internal error running command: io.appium.uiautomator2.common.exceptions.InvalidArgumentException: KeyCharacterMap.getEvents is unable to synthesize KeyEvent sequence out of '233' key code. Consider applying a patch to UiAutomator2 server code or try to synthesize the necessary key event(s) for it manually
  </code></pre>
  
  <p>I read the doc and forum and I added this capability:</p>
  
  <pre><code>desired_caps['unicodeKeyboard'] ='true'
  </code></pre>
  
  <p>But it didn't change anything. I still have same issue.</p>
