When I'm try to share a post on twitter, the title looks like this "Kendrick Lamar is killin' ur vibes" so I change the line 137 in library.php:
$title = get_the_title_rss(get_the_ID());
Instead of this:
$title = get_the_title(get_the_ID());
Now users can share without that HTML tags.
Anyone with similar problem, or other solutions?
