Patch: domains with special characters on Amiga
Cyborg wrote: Hi, on the FTP server of benderirc.de there's a TCP/IP patch (8 KB) for alle TCP/IP stacks for the Amiga. The patch has been tested with Miami on a 68040 Amiga under AmigaOS 3.1.

The patch allows all programs to use ISO strings, for example "sfbücher.de", without having to convert them into the IDN spelling "xn--sfbcher-p2a.de".

Example:
> ping sfbücher.de
PING xn--sfbcher-p2a.de (212.162.56.70): 56 data bytes
64 bytes from 212.162.56.70: icmp_seq=0 ttl=54 time=59.093 ms
64 bytes from 212.162.56.70: icmp_seq=1 ttl=54 time=57.98 ms
64 bytes from 212.162.56.70: icmp_seq=2 ttl=54 time=56.614 ms

--- xn--sfbcher-p2a.de ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 56.614/57.895/59.093 ms

As you can see does the miamiping even recognize the "xn--" spelling and shows it without the program ever get to know this at all! It is really unpatched!

Unfortunately this doesn't work with web browsers as it should but this is because of the browsers and not because of the patch (the reason is described in the readme file).

In short: AWeb for example does show the IDN spelling but uses the ISO way with the vhost. This does the Apache-WebServer not know and the page can't be found. For sfbücher.de I have made this possible.

Therefore here's a call to the IBrowse & AWeb teams to adapt their routines. The ping shows that it's possible (how is written again in the readme file).

YAM and SimpleMail have the same problem on another level but that could be solved the same way.

To make the thing with IDN easier in the future I'll soon make an IDN library available for converting.

The patch archive contains an IDNA converter ISO->PUNYCODE. This way you can provide the browser with the correct name in the meantime.
