Why do you want to use an external libidn while there's a suitable glibc builtin libidn? Passing the new AI_IDN flag flag to getaddrinfo() extends it being IDN-aware. BTW, NI_IDN does the same for getnameinfo(). And yes, I can see your argument as neon is only a library not an application. Bu Maybe you've got a short look to Olaf Kirch's traceroute replacement at ftp://ftp.lst.de/pub/people/okir/traceroute/traceroute-1.0.4.tar.bz2 which is full IDN-capable. Another hint would be the link to the glibc IDN example below, because using flag AI_IDN for gettaddrinfo(räksmörgås.josefsson.org) causes looking up of iesg--rksmrgsa-0zap8p.josefsson.org in DNS. So the ACE is looked up and will be used internally: http://josefsson.org/cgi-bin/viewcvs.cgi/*checkout*/libidn/libc/example.c?content-type=text/plain > $ CHARSET=iso-8859-1 ./example > locale charset `iso-8859-1' > gettaddrinfo(räksmörgås.josefsson.org): > address `217.13.230.178' > canonical name `178.230.13.217.in-addr.dgcsystems.net' > $ Everything should be correct and also perfect - or am I absolutely wrong? Maybe my patch/hack skipped a getnameinfo(), if there's one in. Sorry, I can't really see the problem, because the converting-to-ASCII and the other way round will be well done by getaddrinfo()/getnameinfo() when passing AI_IDN/NI_IDN flags.
