It doesn't seem to accept IDN addresses, though it's able to resolve the punycode equivalent just fine. I was just implementing email and name validation checks for a project myself. Luckily email addresses can at least be validated by a confirmation email; it's the real name field I have no clue what to do with. It's funny that after all these years, we still don't seem to have cracked these basic problems.
