I use Fastmail and have sent myself a testing email with non-ASCII emails, like with Korean or Chinese characters. So 안녕@mydomain works with Fastmail.

So apparently if you host your own domain with them they do?
However, they don't appear to support it for [email protected]. Either for sign up, or for live delivery. http://imgur.com/a/Otf4f (see both images)
Try sending to 안녕@mydomain from a gmail account...it looks like they may not be supporting SMTPUTF8 correctly. Which could result in sending-to-yourself working, but not from an outside source.
