Description

Page not found handling is broken for domains with non-ascii names:
1. You have a domain name like áéćž.com
2. You have the following error handling configuration:

errorHandling:
  - errorCode: 404
    errorHandler: Page
    errorContentSource: 't3://page?uid=6'

The result for non-existing pages is:

503
Page Not Found
External error page could not be retrieved. Client error: `GET https://áéćž.com/404/` resulted in
a `401 Unauthorized` response: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8">
<title>Seite nicht gefunden</title> <meta nam (truncated...)

The problem is in EXT:core/Classes/Error/PageErrorHandler/PageContentErrorHandler.php, near line 103:

             $this->pageUid = $urlParams['pageuid'] = (int)($urlParams['pageuid'] ?? 0);
             $resolvedUrl = $this->resolveUrl($request, $urlParams);

The urls needs to be converted to punycode before passing it to the request. It should fetch https://xn--1caq4gov.com/404/ instead of https://áéćž.com/404/.

We use squid proxy for non-local sites. Not sure if it is important.

\TYPO3\CMS\Linkvalidator\Linktype\ExternalLinktype::preprocessUrl() does it correctly.
