Configuration for breadcrumb separator

It would be great to have a config page/ui to set a breadcrumb separator.

Temporary Template.php solution (replace MYTHEMESNAME with your theme folder name)

function MYTHEMESNAME_delta_blocks_breadcrumb($variables) {
  $output = '';

  if (!empty($variables['breadcrumb'])) {
    if ($variables['breadcrumb_current']) {
      $variables['breadcrumb'][] = l(drupal_get_title(), current_path(), array('html' => TRUE));
    }

    $output = '<div id="breadcrumb" class="clearfix"><ul class="breadcrumb">';
    $switch = array('odd' => 'even', 'even' => 'odd');
    $zebra = 'even';
    $last = count($variables['breadcrumb']) - 1;

    foreach ($variables['breadcrumb'] as $key => $item) {
      $zebra = $switch[$zebra];
      $attributes['class'] = array('depth-' . ($key + 1), $zebra);

      if ($key == 0) {
        $attributes['class'][] = 'first';
      }

      if ($key == $last) {
        $attributes['class'][] = 'last';
        $output .= '<li' . drupal_attributes($attributes) . '>' . $item . '</li>' . '';
      }

      else {
        $output .= '<li' . drupal_attributes($attributes) . $item . ' > </li>';
      }
    }

    $output .= '</ul></div>';
  }

  if (drupal_is_front_page()) {
    $output = '<h2 class="element-invisible">' . t('You are here') . '</h2>';

    $output .= '<div class="breadcrumb">Startseite</div>';
 }

  return $output;
}
