Feed validation fails if category name contains an apostrophe

Hi Bruno,

For the title, GN Publisher calls wp_title_rss()

I’m a little hesitant to change the default behavior of how WP outputs the title.

When you ran it through the RSS Validator, did it flag it as an error (not valid) or a warning?

Hi Chris,
Thank you for your answer.
The validator returns an error (not valid) at line 10 when “& apos;” is used in de <title> tag.
To avoid this issue, I have renamed the category name in the WP admin: I replaced the apostrophe with “& #8217;”.

Are you comfortable with that as a solution, or would you like me to continue investigating other potential solutions?

Apparently not very many publishers have apostrophes included in the category name, since this has never come up before ??

Hi Chris,
I’ve investigated more and find out that if I set a title with the ‘ char (char code #39), WP replaces it with an ’ (char code #8217) and encodes it with HTML entity name ‘rsquo’ in “get_wp_title_rss” function.
So I wrote a filter :

add_filter('document_title', function($title){
	$title = str_replace(['’', '& rsquo;'], ['& #8217;', '& #8217;'], $title);
	return $title;
});

This patch works for me and I don’t need a plugin evolution.

Note that I use WordPress in French.

Awesome – yep, I was thinking along the same lines as a potential solution! Thanks for working this out and sharing,

Chris
