WP Preserve Backslashes

I created a WordPress plugin based on a personal dilemma I ran into with my site being stripped of backslashes.

Upon post save, it converts backslashes to HTML entity ] which is what will be stored in the database.

The plugin is available on GitHub at
Here’s the function if you want to just drop it in your functions.php file instead of installing it as a plugin.

function wppb_keepbackslash($PostID) {
    $thePost = get_post($PostID);
    $Content = str_replace('\\', '\', $thePost->post_content);
    // unhook this function so it doesn't loop infinitely
    remove_action( 'save_post', 'wppb_keepbackslash' );
    $UpdatedPost = array (
          'ID'           => $PostID,
          'post_title'   => $thePost->post_title,
          'post_content' => $Content
  wp_update_post( $UpdatedPost );
/** if (is_wp_error($post_id)) {
 $post_id=   wp_update_post( $UpdatedPost );
        $errors = $post_id->get_error_messages();
        foreach ($errors as $error) {
                echo $error;
}   **/
    // re-hook this function
    add_action( 'save_post', 'wppb_keepbackslash' );
add_action('save_post', 'wppb_keepbackslash' ); // Update Content when saving content
