``/es`` *won't match this route*

..note::

Since Symfony 3.2, you can enable UTF-8 route matching by enabling the `utf8`

parameter when declaring or importing routes. This will make e.g. a `.` in

requirements match any UTF-8 characters instead of just a single byte.

The flag is automatically enabled whenever a route or a requirement use any

non-ASCII UTF-8 characters or a `PCRE Unicode property`_ (``\p{xx}``,

``\P{xx}`` or ``\X``). Note that this behavior is deprecated and a

`LogicException` will be thrown insteand in 4.0 unless you explicitly turn

on the `utf8` parameter.

..tip::

The route requirements can also include container parameters, as explained

For really complex requirements, you can use dynamic expressions to match *any*

information on the request. See:doc:`/routing/conditions`.
