实现这一点的最佳方法是删除默认的sanitize\\u标题过滤器，并将其替换为您的过滤器，这将正确编码这些字符。下面是using accents in permalinks.

示例：

remove_filter( \'sanitize_title\', \'sanitize_title_with_dashes\');
add_filter( \'sanitize_title\', \'restore_raw_title\', 9, 3 );
function sweURLtoCHAR($text)
{
  $url=array(
    "%C3%81","%C3%A1",
    "%C3%8D","%C3%AD"
  );
  $char=array(
     "Á","á",
     "Í","í"
  );

  $str = str_replace($char,$url,$text);
  $str_new = str_replace(" ", "", $str);
  return strtolower($str_new);
}
function restore_raw_title( $title, $raw_title, $context ) {
  if ( $context == \'save\' )
   return sweURLtoCHAR($raw_title);
  else {
   $title_new = str_replace(" ", "", $title);
   return strtolower($title_new);
  }
}
