    When the initiative is set in php.ini encodings other than coding blog, watching the problem with the encoding of XMLRPC applications (for example – Live Writer) and in all admin-AJAX responses.

    To resolve the error:

    • file wp-includes/class-IXR.php, now: 
      function output($xml)
{
      $xml = '<?xml version="1.0"?>'."\n".$xml;
      $length = strlen($xml);
      header('Connection: close');
      header('Content-Type: text/xml;', true);
      header('Content-Length: '.$length);
      header('Date: '.date('r'));
      echo $xml;
      exit;
}

      correct version:

      function output($xml)
{
      $xml = '<?xml version="1.0" encoding="'.get_option('blog_charset').'"?'.'>'."\n".$xml;
      $length = strlen($xml);
      header('Connection: close');
      header('Content-Type: text/xml; charset=' . get_option('blog_charset'), true);
      header('Content-Length: '.$length);
      header('Date: '.date(DATE_RFC1123));
      echo $xml;
      exit;
}

    • wp-includes/class-wp-admin-ajax-response.php, now: 
      function send() {
    header('Content-Type: text/xml');
    echo "<?xml version='1.0' standalone='yes'?><wp_ajax>";
    foreach ( (array) $this->responses as $response )
        echo $response;
    echo '</wp_ajax>';
    die();
}

      correct version:

      function send() {
    $xml = "<?xml version='1.0' encoding='" . get_option('blog_charset') . "' standalone='yes'?><wp_ajax>";
    foreach ( (array) $this->responses as $response )
        $xml .= $response;
    $xml .= '</wp_ajax>';
    $length = strlen($xml);
    header('Content-Type: text/xml; charset=' . get_option('blog_charset'));
    header('Content-Length: '.$length);
    header('Date: '.date(DATE_RFC1123));
    echo $xml;
    die();
}

    And when updated plugins. wp-admin/includes/template.php now:

    function iframe_header( $title = '', $limit_styles = false ) {
    show_admin_bar( false );
    global $hook_suffix, $current_screen, $current_user, $admin_body_class, $wp_locale;
    $admin_body_class = preg_replace('/[^a-z0-9_-]+/i', '-', $hook_suffix);
    $admin_body_class .= ' iframe';

<html xmlns="http://www.w3.org/1999/xhtml" <?php do_action('admin_xml_ns'); ?> <?php language_attributes(); ?>>

<?php

    correct version:

    function iframe_header( $title = '', $limit_styles = false ) {
    show_admin_bar( false );
    global $hook_suffix, $current_screen, $current_user, $admin_body_class, $wp_locale;
    $admin_body_class = preg_replace('/[^a-z0-9_-]+/i', '-', $hook_suffix);
    $admin_body_class .= ' iframe';

    header('Connection: close');
    header('Content-Type: text/html; charset=' . get_option('blog_charset'), true);
    header('Expires: '.date(DATE_RFC1123));
    header('Date: '.date(DATE_RFC1123));
    header('Cache-Control: no-store, no-cache, must-revalidate');
    header('Cache-Control: post-check=0, pre-check=0', FALSE);
    header('Pragma: no-cache');
