`nl2br`

The nl2br filter inserts HTML line breaks before all newlines in a string:

.. code-block:: html+twig

{{ "I like Twig.\nYou will like it too."|nl2br }}
{# outputs

    I like Twig.

    You will like it too.

#}

.. note::

The ``nl2br`` filter pre-escapes the input before applying the
transformation.
