I'm not sure I understand correctly what "%-hex encoded UTF-8 encoded Unicode in URLs" means, but here's a pointer that could be useful: http://www.alis.com:8085/~yergeau/url-00.html >The URLs you point us to are all in your personal >area (~yergeau) on alis.com. Normal. That's the area I control. > Why aren't any of >the other URLs on the alis site internationalized, >since it is compatible with current browsers? Perhaps it has to do with lack of standardization? Were there that many HTTP/1.1 implementations before there was a standard, or at least some language in a serious draft, to point the way? >Did you try any browsers that didn't work? No. I tried 3 installed on my machine, they all worked. I thought publishing the URL would rather quickly get out reports of browsers that failed. None so far. > Do any of the browsers >display the URLs as anything other than %xx%xx%xx in the 'location' box? How would they? Lacking a standard mapping from octets to characters for xx>127, what characters could they display. For what it's worth, Tango correctly displays the first link destination in the status bar when the mouse is over the anchor. >Is there any software anywhere in the world that actually generates >URLs like these? All of the examples seem to be carefully >hand-constructed. Valid point. We seem to have the client side settled (works with unmodified browsers), let's now deal with servers. You want software, so I wrote some. Going to the following place: ftp://ftp.alis.com/pub/ietf/url/ you will find a Perl script and two mapping files for two character sets (ISO 8859-1 and CP850). Installing the script and one of the mappings on a Unix server should let one create UTF-8 URLs at will. Instructions are in the script. I've recreated the URL pointed to by the document at http://www.alis.com:8085/~yergeau/url_utf8.htm so that it is *not* anymore a "carefully hand-constructed" URL, but one created using software purposefully written for the task of creating UTF-8 URLs. The script is all that's needed, the HTTP server is unmodified. Not that this is the only way to go, of course. So we do have a server-side implementation now. -- François Yergeau <yergeau@alis.com> Alis Technologies Inc., Montréal Tél : +1 (514) 747-2547 Fax : +1 (514) 747-2561
