How to replace quotes in wordpress?

Question

WordPress

Greetings!
I ran into a problem that instead of straight quotes (""), there are Christmas trees ("") on the whole site
, I googled it, found a way to replace it (so as not to shovel the entire site):

add_filter( 'the_content' , 'my_wptexturize' );
function my_wptexturize( $content ) {
$symbol_table = array('«' => '"', '»' => '"', '«' => '"', '»' => '"', '«' => '"', '»' => '"', '«' => '"', '»' => '&#34');
$content = strtr( $content, $symbol_table );
return $content;
}

after that, quotes were replaced somewhere, but somewhere not
, what's the problem?

Hello!
Try using Better Search Replace to replace the quotes. Select all database tables. Don't forget to create a database dump (updraft plus backup).
Well, or through phpmyadmin, download the database, change the characters through search & replace (sublime ctrl + h) and fill in the database back (I don’t really recommend it, because sometimes it can break the database due to serialized data). Better plugin
