title: Redactor(WYSIWYG editor) automatically converts Chinese to string in english
body: <p>I'm using redactor now for a website in Chinese. However, when you type Chinese in the editor like (哈哈哈 - which is "hahaha") - it is automatically converted to "ha ha ha" after saving. </p>
  
  <p>It only happens on my phone (safari in iOS9 but not desktop - chrome). The code is very long, I tried to go through it but couldn't find anything. </p>
  
  <p>It seems like certain Chinese characters got sanitized and messed up. Is there anything particular that I should be looking for?</p>
