Description Klaus Singvogel 2006-02-13 08:59:20 UTC 
I tried to download from a German Umlaut-Domain, and noticed that curl is not capable to translate the domain into a Punycode encoding, and therefore the download failed.

Example:
   curl http://www.gunnar-gröbel.de/assets/images/Verkehr/239.gif -o 239.gif
should be converted (internaly) to:
   curl http://www.xn--gunnar-grbel-djb.de/assets/images/Verkehr/239.gif  -o 239.gif

Please note: konqueror and mozilla can display 'http://www.gunnar-gröbel.de/assets/images/Verkehr/239.gif'

For more information about Punycode look at http://www.ietf.org/rfc/rfc3492.txt or http://en.wikipedia.org/wiki/Punycode

There already is IDN support in curl, it's just not enabled in our package ;)

Andreas, can I still submit it an IDN-enabled curl package? 



BTW:
$ wget http://www.gunnar-gröbel.de/assets/images/Verkehr/239.gif
--12:44:49--  http://www.gunnar-gr%C3%B6bel.de/assets/images/Verkehr/239.gif
           => `239.gif'
