symfony 2 twig limit the length of the text and put three dots

Question

How can I limit the length of the text, e.g., 50, and put three dots in the display?

{% if myentity.text|length > 50 %}

{% block td_text %} {{ myentity.text}

Bugginess* in the new Drupal 8 capabilities here inspired us to write our own:

<a href="{{ view_node }}">{% if title|length > 32 %}{% set title_array = title|split(' ') %}{% set title_word_count = 0 %}{% for ta in title_array %}{% set word_count = ta|length %}{% if title_word_count < 32 %}{% set title_word_count = title_word_count + word_count %}{{ ta }} {% endif %}{% endfor %}...{% else %}{{ title }}{% endif %}</a>

This takes into consideration both words and characters (*the "word boundary" setting in D8 was displaying nothing).
