Yoast SEO: https://wordpress.org/plugins/wordpress-seo/

For example:

The default title variable string is:

%%title%% %%page%% %%sep%% %%sitename%%

where %%sep%% can be set according to your any symbol.

Thanks for the asnwer but is not what i need. I already use yoast plugin. I want to use “-” in page.

Here https://demo.tagdiv.com/newspaper/smart-list-style-5/ the post title “Smart List – Style 5”. Yoast will not change the “–” on the site only in the <meta property=og:title content

If I understood your question correctly. What you’re asking is it’s not Theme driven. This function is controlled by the WordPress engine:

Try in your function.php file add:

add_filter('document_title_separator', function() { return 'YOUR_SYMBOL';} );
