title: PHP regular expression any kind of letter from any language
body: <p>I'm trying to create my own routing in php using regex,
  my example returns true when the name is in latain, but when the name is in arabic returns false</p>
  
  <pre><code>preg_match('#^(en/users/(?&lt;name&gt;[\p{L}\p{Nd}\_\-\+]+))$#', 'en/users/علي+عثمان')
  </code></pre>
