|slice filter does not work with special characters

Question

I try to use the slice filter in order to limit a link to a specific amount of characters. The field that I render is a link field and my code is the following:

{% set title_text = title|render|striptags %}
<span> 
     {{ title_text|length > 65 ?
         title_text|slice(0,65)  :
         title_text|striptags}}
</span>

Unforturnately some characters like the apostrophe are not rendered appropriately.

So instead of rendering "I've learned", they render "I& #039;ve learned"

Answer 1

Actually the culprit is |striptags

The problem with using twig's |striptags is double encoding of html entities, not markup, so & becomes & and then & – Berdir

If your setup relies on you running striptags last, you will need to do this all of this magic in a preprocess function with php setting a variable here and then printing your formatted variable on twig.
