Replace Dashes Before Title in Page List

by

I want to replace the dashes before the page title in the dashboard page list. For each hierarchy below the first, a dash is prepended (as seen in the screenshot below):

enter image description here

It seems that the filter the_title does not affect these dashes:

add_filter( 'the_title', 'change_my_title' );
function change_my_title( $title ) {
    return str_replace( '–', $title );
    // nor preg_replace or – or — work
}

So my question is: How can I replace these dashes with something specific? Do I really have to implement a custom list table or meddle around with jQuery?

You can’t change dashes using any filter because there is no filter available to change it.

but still you can change this using jQuery put this code inside functions.php

add_action('admin_head',function(){


global $pagenow;

// check current page.
if( $pagenow == 'edit.php' ){ ?>

    <script>

        jQuery(function($){

            var post_title = $('.wp-list-table').find('a.row-title');
            $.each(post_title,function(index,em){
                var text = $(em).html();
                // Replace all dashes to * 
                $(em).html(text.replace(/—/g ,'*'));
            });
        });

    </script>
    <?php
    }
});
