  • Blog Post: EAI (Email Address Internationalization) address validation

    I've been asked a few times how to verify how an international email address is well formed. International email addresses have unicode in the local part of the address (before the @), or in the domain name, or both. This problem is actually a bit trickier than many people expect because actual rules...
  • Blog Post: Email Address Internationalization, aka: using UTF-8 in email, RFCs are published

    I helped write an RFC ( http://www.rfc-editor.org/rfc/rfc6532.txt) :) (Well, I've had input before, but this is the first time as an author). The core Email Address Internationalization RFCs, which allow UTF-8 in email addresses and use UTF-8 in SMTP by default, were published back in February. I...
  • Blog Post: IDNA - Is it fussball or fußball?

    [Update - Note: A coworker pointed out that it's really Fussball or Fußball, since it's a noun. I knew that, I'm just using the lower case here because domain names get lower cased, which is a seperate issue and I didn't want to complicate the example.] IDNA2008 (which is something of a misnomer...
  • Blog Post: Thoughts About Email Addresses with EAI (Email Address Internationalization)

    The EAI Working Group ( http://datatracker.ietf.org/wg/eai/charter/ ) is making rapid progress toward standardizing Unicode email addresses. Unicode email addresses are a terrific feature for people in many countries that don't use Latin/ASCII as a native script. Ironically, in the US its easy to miss...
  • Blog Post: 4 IDN ccTLDs (country code top level domain)s have been approved.

    This is old news, but I didn't blog about it yet. 4 IDN ccTLDs have been approved: http://icann.org/en/announcements/announcement-21jan10-en.htm Cyrillic Script Russian Federation (RU): рф Arabic Script Egypt (EG): مصر Saudi Arabia (SA): السعودية United Arab Emirates (AE): امارات
  • Blog Post: The FUD of IDN and Homographs

    I was pointed to this article http://www.microsofttranslator.com/BV.aspx?ref=Internal&a=http%3a%2f%2fwww.bortzmeyer.org%2fidn-et-phishing.html about IDN and homographs, which points out that most of the fear around IDN and phishing is unfounded. Seemed like a good reference (thanks, Mark), so I'm...
  • Blog Post: 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 the EAI standard. I've heard a target of November...
  • Blog Post: 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 or character based security when it was limited...
  • Blog Post: 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 email would work, and I encourage people to take...
