Why is glibc needed to support such IDN? I think DNS does handle the
current domain name.
If user want to use IDN, he needs to input locale strings, and
application convert from locale to unicode, then normalize through
nameprep, then convert to alphabetical Punycode domain name. So which
string types does gethostbyname() get? Unicode? Locale strings?
Normalized nameprep strings? I think "nothing". DNS handles
alphabetical domain name which is currently used.
And are there any implementations which have IDN-supported
gethostbyname() ? With conforming to standards, is it OK to support?
