SSL for International Domain Names

I didn't know that you couldn't buy SSL certs for international domain names (naive americans). I have only ever bought them for .com names. However, Thawte just sent me an email, saying that you now can buy SSL certs for IDN names:

Internationalized Domain Names, or IDNs, are web addresses in your own language which until recently were not supported by browsers and email clients.
thawte is the first Certification Authority to provide SSL certificates capable of securing Internationalized Domain Names. This capability extends across our full range of SSL certificate including SSL123 Certificates, SSL Web Server Certificates and SGC SuperCerts.
