+``url_encode``
+==============
+
+.. versionadded:: 1.12.3
+ Support for encoding an array as query string was added in Twig 1.12.3.
+
+.. versionadded:: 1.16.0
+ The ``raw`` argument was removed in Twig 1.16.0. Twig now always encodes
+ according to RFC 3986.
+
+The ``url_encode`` filter percent encodes a given string as URL segment
+or an array as query string:
+
+.. code-block:: jinja
+
+ {{ "path-seg*ment"|url_encode }}
+ {# outputs "path-seg%2Ament" #}
+
+ {{ "string with spaces"|url_encode }}
+ {# outputs "string%20with%20spaces" #}
+
+ {{ {'param': 'value', 'foo': 'bar'}|url_encode }}
+ {# outputs "param=value&foo=bar" #}
+
+.. note::
+
+ Internally, Twig uses the PHP `urlencode`_ (or `rawurlencode`_ if you pass
+ ``true`` as the first parameter) or the `http_build_query`_ function. Note
+ that as of Twig 1.16.0, ``urlencode`` **always** uses ``rawurlencode`` (the
+ ``raw`` argument was removed.)
