I’m using the function truncate to show part of a text, next to this function I added the function html_safe so that the text does not display unwanted characters. But when the text is greater than the limit I set, length: 150, undesirable characters reappear.
I would like a solution for this, truncate the text but do not show unwanted characters.
<%= truncate(service.description.html_safe, length: 15, )
0
<%= truncate(sanitize service.description, length: 15, ) %>
Breathes with the method sanitize(html, options = {})

A Gem truncate_html maybe it’ll solve your problem
Input example: <p>This is <em>my <strong>first</strong> post</em></p>
Using the Gem: <%= truncate_html post.title, :length => 15 %>
Exit: <p>This is <em>my <strong>fir…</strong></em></p>
It truncates the text as expected, what happens is that when the text is greater than the limit imposed by length it returns unwanted characters, if it is less than that it returns the text normally!

length: 150 or 15? You have one in the text and one in the code
