title: create URL slugs for chinese characters. Using PHP
body: <p>My users sometimes use chinese characters for the title of their input.</p>
  
  <p>My slugs are in the format of <code>/stories/:id-:name</code> where an example could be <code>/stories/1-i-love-php</code>.</p>
  
  <p>How do I allow chinese characters?</p>
  
  <p>I have googled and found the japanese version of this answer over <a href="https://stackoverflow.com/questions/21506016/trying-to-generate-url-slugs-with-php-regex-japanese-characters-not-going-throu">here</a>.</p>
  
  <p>Don't quite understand Japanese, so I am asking about the chinese version.</p>
  
  <p>Thank you.</p>
