**Description** <!-- A clear and concise description of the new feature. --> I was trying to replace [the `truncate` filter from `twig/extensions`](https://github.com/twigphp/Twig-extensions/blob/master/src/TextExtension.php#L36) with the new `u` filter, but it looks like [`u.truncate` doesn’t have a `preserve` option](https://github.com/symfony/symfony/blob/master/src/Symfony/Component/String/AbstractString.php#L625), is there a way to achieve the same thing? If not, I could add the parameter to the `truncate` method. **Example** <!-- A simple example of the new feature in action (include PHP code, YAML config, etc.) If the new feature changes an existing feature, include a simple before/after comparison. --> With `twig/extensions`: ```twig {{ "Hello World!"|truncate(7, true) }} // Hello World! ``` With `u` filter: ```twig {{ "Hello World!"|u.truncate(7) }} // Hello W ```
