fatal error when using punycode in URLs

[s-thet]

Trying to load http://www.köln.de punycode encoded results in warnings and fatal errors.

<?php
$url = 'http://www.xn--kln-sna.de';
$req = new \http\Client\Request('GET', $url);
$client = (new \http\Client())->enqueue($req)->send();

PHP Warning:  http\Client\Request::__construct(): Failed to parse host; unexpected '-' at pos 7 in 'www.xn--kln-sna.de'
PHP Fatal error:  Uncaught http\Exception\RuntimeException: http\Client::enqueue(): Cannot request empty URL
Stack trace:
#0 ...: http\Client->enqueue(Object(http\Client\Request))
#1 {main}

In the meantime, if your build supports IDNA, you can use the NFC-UTF8 URL as-is.
