Untranslatable strings

It is not possible to translate strings 'Yes' and 'No'

code from browscap.module line 389:

      if ($useragent->is_crawler) {
        $is_crawler = 'Yes';
      } else {
        $is_crawler = 'No';
      }

should be:

      if ($useragent->is_crawler) {
        $is_crawler = t('Yes');
      } else {
        $is_crawler = t('No');
      }
