Adding IDN support

I am the technical director here at Verisign responsible
for the development of a plug-in to IE, Outlook and
Outlook Express to provide support for IDNs
("International Domain Names") As part of our
development effort we have packaged an open source C
library that can be integrated into application such as
FileZilla. This completely free library provides
all the necessary encoding/decoding required when
taking a domain name in non-ASCII characters and
converting it so that DNS can understand it.

Companies such as SmartFTP ( and
CoreFTP ( have taken this library and
have integrated it into their products with others
currently under development.

With Netscape, Mozilla, Firebird and Camino now also
support IDNs natively based on the suggestion of a
collegue I am posting this request.

IDNs are now being offered by most of the major gTLDs
as well as ccTLDs.

IDNs being supported in dotCom and dotNet they are
now also supported by the following ccTLDs: dotNo,
dotSe, dotDk, dotDe, dotCh, dotCn, dotHk, dotJp, dotKr,
dotTw, dotVn, dotCc and dotTv. Shortly dotLt, dotInfo
and dotAt will also be making IDNs available in their
respective markets.

Attached to this message is our SDK which can be
reviewed for suitability of purpose. Unfortunately the
attached ZIP file includes both our Java as well as C
implementations so you'll need to sort through to pick
out the pieces of the C lib.

Finally, we have set up an external FTP Server to
faciliate testing and I would be pleased to provide
suitable information should it be of value.

Thank you for your consideration.
