title: International Url with htaccess
body: <p>I have in my <code>.htaccess</code> file this rule:</p>
  
  <pre><code>RewriteRule ^([a-z0-9-]+)/([\p{L}0-9-]+)$ /cat/article.php?author=$1&amp;title=$2 [QSA,L]
  </code></pre>
  
  <p>which matches <code>http://www.example.com/toto6-titi/tata-tutu2</code> for example.</p>
  
  <p>Now, I want to have any kind of character in any alphabet, so I change my rewrite rule to:</p>
  
  <pre><code>RewriteRule ^([\p{L}0-9-]+)/([\p{L}0-9-]+)$ /cat/article.php?author=$1&amp;title=$2 [QSA,L]
  </code></pre>
  
  <p><code>http://www.example.com/toto6-titi/tata-tutu2</code> and similar kinds of URL are still working but "international" URLs like <code>http://www.example.com/啊/安</code> still don't :(</p>
  
  <p>I am on wamp with Apache 2.2.3, PHP 5.6.25 and MySQL 5.6.17</p>
  
  <p>My <code>.htaccess</code> file is encoded in UTF8</p>
  
  <p>What am I missing?</p>
