+Unicode Routing Support
+~~~~~~~~~~~~~~~~~~~~~~~
+
+.. versionadded:: 3.2
+    UTF-8 support for route paths and requirements was introduced in
+    Symfony 3.2.
+
+The Routing component supports UTF-8 characters in route paths and requirements.
+Thanks to the ``utf8`` route option, you can make Symfony match and generate
+routes with UTF-8 characters:
+
+.. configuration-block::
+
+  .. code-block:: php-annotations
+
+        // src/AppBundle/Controller/DefaultController.php
+        namespace AppBundle\Controller;
+
+        use Symfony\Bundle\FrameworkBundle\Controller\Controller;
+        use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
+
+        class DefaultController extends Controller
+        {
+            /**
+             *
+             * @Route("/category/{name}", name="route1", options={"utf8": true})
+             *
+             */
+            public function categoryAction()
+            {
+                // ...
+            }
+
+  .. code-block:: yaml
+
+      # routes.yml
+      route1:
+          path:     /category/{name}
+          defaults: { _controller: 'AppBundle:Default:category' }
+          options:
+              utf8: true
+
+  .. code-block:: xml
+
+        <!-- app/config/routing.xml -->

+
+            <route id="route1" path="/category/{name}">
+                <default key="_controller">AppBundle:Default:category</default>
+                <option key="utf8">true</option>
+            </route>
+        </routes>

+      use Symfony\Component\Routing\RouteCollection;
+      use Symfony\Component\Routing\Route;
+
+      $collection = new RouteCollection();
+      $collection->add('route1', new Route('/category/{name}',
+          array(
+              '_controller' => 'AppBundle:Default:category',
+          ),
+          array(),
+          array(
+              'utf8' => true,
+          )
+      );
+
+      // ...
+
+      return $collection;
+
+
+In this route, the ``utf8`` option set to ``true`` makes Symfony consider the
+``.`` requirement to match any UTF-8 characters instead of just a single
+byte character. This means that so the following URLs would match:
+``/category/日本語``, ``/category/فارسی``, ``/category/한국어``, etc. In case you
+are wondering, this option also allows to include and match emojis in URLs.

+
+This second example describes how you can use UTF-8 strings as a routing
+requirements.
+
+.. note::
+
+    In Symfony 3.2 there is no need to set this ``utf8`` option explicitly.
+    As soon as Symfony finds a UTF-8 character in the route path or requirements,
+    it will turn the UTF-8 support automatically. In addition to UTF-8
+    characters, the Routing component also supports all the `PCRE Unicode properties`_,
+    which are escape sequences that match generic character types. For
+    example, ``\p{Lu}`` matches any uppercase character in any language,
+    ``\p{Greek}`` matches any Greek character, ``\P{Han}`` matches any character
+    not included in the Chinese Han script.
