IDNA2008 / IDNAbis on Windows 7, Vista, Net, etc.

Some people have asked what they should do to support IDNA2008 on Microsoft platforms. We provide IdnToAscii() and related functions in the Windows SDK. That's available natively on Vista+, and through idndl.dll on earlier platforms. Idndl is shipped

Oversimplification of EAI/IMA (International eMail Addresses)

A couple months ago I blogged about EAI Email Address Internationalization/Internationalized Email Addresses (EAI/IMA) and felt like blogging again. China's been very interested in non-ASCII email addresses for some time, and is working hard to adopt

Unicode, IDN (IDNA), EAI (IMA) and Homograph Security

I wrote about IDN & Security before http://blogs.msdn.com/shawnste/archive/2005/03/03/384692.aspx but thought I'd share some of my more updated views about security of URLs/IDN/Unicode/Email addresses. People haven't really bothered much with DNS

Email Address Internationalization / Internationalized eMail Addresses (EAI/IMA)

With the IDN work for Internationalized Domain Names using characters beyond ASCII, it is only natural to tackle the problem of Internationalized Internet eMail. Some smart people have been working on an IETF working group to figure out how non-ASCII

Rambling about RFC 4690 and IDN

There's a reasonably new RFC 4690 ( http://www.ietf.org/rfc/rfc4690.txt ) that raises a bunch of questions about IDN names and Unicode regarding such things as confusable characters and other issues. Some of those are also discussed in Unicode TR36 "Unicode

IDN Test URLs

A colleague gave me some URLs to use for testing IDN. I don't vouch for any of these sites, and some are obvious ads and some may be inappropriate (since I can't read them), but maybe they'll be helpful for testing. Additionally some sites could be phishing,

Does your web site die when it sees unexpected languages?

Recently I've seen a spate of bugs involving client-server web applications related to the user locale. Windows Vista has added a ton of locales that weren't there in XP or Server 2003 or Microsoft.Net v2.0. Additionally users can create and use their

Does "Everyone" Use IDN?

Recently it came to my attention that arbitrary implementation of IDN can break existing networks. Particularly on Intranets machine names have not always been restricted to ASCII. In many of our markets it is quite common to have non-ASCII machine names.

How Come IdnToAscii Fails For String XXXX?

I'm often asked why particular strings fail the IdnToAscii function. The answer is "because its not a legal IDN name, that's why" :-) But why aren't some strings legal IDN names? Some rules act on the "label" level. In www.microsoft.com www, microsoft

IDN Mitigation API dll needs to be explicitly linked
