Again about UTF-8 and the display at #

Hmmm It’s my fault. Your plugin works perfectly.

I checked function.php and found that I had added a few lines of code. Looks like something is not ok with what I added.

add_filter( 'a_z_listing_item_index_letter', 'my_a_z_index_filter', 10, 3 );

function my_a_z_index_filter( $index_letters, $item, $item_type ) {
    // make sure we're filtering the right post type
    if ( 'page' === get_post_type( $item ) ) {
        // pull the title and get the first letter of the second word
        $full_name = explode( ' / ', $item->post_title );

        // the last word is in the last element of $title_parts so check it is there
        $last_name = array_pop( $full_name );

        // ensure we actually found a last name
        if ( $last_name )  {
            // cut the first letter out for our index
            $index = substr( $last_name, 0, 1 );

            // set up a new empty array overwriting the old indices
            $index_letters = array( $index );
        }
    }

    // return the indices item's indices
    return $index_letters;
}

Can you please help me?

I’m using this code in another index on the site. I need to remove the first two words in the title so that the sorting is done by the third word. Something like this:

XXX YYY A
XXX YYY B
XXX YYY C

I do not want all articles to appear in X, but depending on A, B, C I want titles to appear in letter A, B, C.

The above code works for this need but it seems that it disturbs the diacritics in the title.

Thank you! It works like a charm!
